Google Geo Chart Co-ordinate Plotting Tutorial

Sometimes you read something so useful on the “web”, thanks, it opens your eyes to a whole new way to use something you had already written as a web application, just with some small tweaks.

So it was today, building on the Google Chart Geo Chart work we’d last visited with our PHP interfacing to it mentioned in Google Geo and Intensity Chart via Clipboard Co-ordinates Tutorial.

We already knew it could …

highlight countries of interest in the world
highlight some regions of interest within some countries … but discoveries today involved …
the Google Chart Geo Chart can recognize some place names (it knows) and plot them … or …
the Google Chart Geo Chart can be supplied latitude and longitude data to plot places on a map of the world

… and it is this latter capability that is most exciting to us. We can see “contextual” benefits interfacing to this new functionality we’ve added into our Geo Chart interfacing’s live run‘s geo_chart.php changed this way.

Stay tuned for this new tool helping contextualise some other web applications involving latitude and longitude geographical information.

… in that …

Pie Chart and Geo Chart ask for a non-numerical,numerical set of data sets
Geo Chart and Intensity Map (or chart) are both concerned with a Country (Code or Name) non-numerical first data set member
Geo Chart can provide the Intensity Map (or chart) with help regarding an onclick “select” event chance to enhance its functionality

In this regard, it will be no surprise to many of you that with today’s changes to Geo Chart and Intensity Map (or chart) PHP interfacings we take on today can be shown to you, again, using that data source (helper) we’ll present, again, today, below …

There was that “clipboard” and URL compatibility worked on today, and, biting the bullet, getting great help from this useful link, thanks, we improved the Intensity Map (or Chart) input requirements, allowing (quietly) a user to enter whole Country Names, and behind the scenes we’ll try to map these to the ISO-2 character country codes the Intensity Map (or Chart) requires as input data.

Google Pie Chart via Clipboard Co-ordinates Tutorial

Yesterday’s Google Map Chart via Clipboard Co-ordinates Tutorial was a good precursor to today’s work interfacing this time to the Google Chart Pie Chart.

With this work, we’ve started refining the clipboard “smarts” by looking for linefeeds … in Javascript thoughts …

String.fromCharCode(10)

… and as the data exits the Javascript prompt window on its way, before navigating back to the PHP itself, we can check for too many fields to the right of the data, and truncate the clipboard data, as necessary. Along the way, we may be able to reject any header records with this same approach. We can check for no numerical fields here. Business specific logic can be applied here too. With a Pie Chart, the original data, or the user, may be tempted to place “%” after the numerical data, and we can take the opportunity to weed these out. Also, with the character data, it may be delimited by a double quote (ie. within “”), and with this knowledge in mind, we may be able to weed out confusing additional commas that could confuse us with the clipboard comma separated value format of the data.

The lesson here, is to “validate early” and it could be good to “validate often” as well. Real data can be strange indeed.

Our PHP Google Chart Pie Chart interface is pie_chart.php changed this way for today’s work, that you can try yourself at this live run link.

Our PHP helper csv.php changed this way for today’s work.

primary data source that you enter a comma separated values list for the [place,lat,long] data sets (yourself, via the computer keyboard) … as well as a …
“subset” of a secondary data source, that you access, more than likely, using you computer device’s clipboard

The invention of the clipboard was a brilliant step. Before it, we were so beholden to programmers to get tailored work done, and though it’s sad that so many of you get on without us (cough, cough) … well … we were being overworked anyway … and there was that project to “make the morning breakfast coffee before you even know you wanted it” to get onto … finally.

Perhaps we all forget now what the clipboard has meant, for so many of us. It is the freedom of “copy and paste”, the individualism tool of content creation.

Yesterday’s functionality idea is a case in point. “Secondary data sources” are, by definition, out of your control, as to what the content of a web page is. Notice how, yesterday, we made some content that was (s)ftp transferred over to the rjmprogramming.com.au domain via … yes, you guessed it …

me copying (off the mapbox.com website, thanks, as part of the contents of a webpage) … then …

But there you are, an intelligent human, able to determine for yourself the data you are interested in (quite often not the entire contents of a webpage, as yesterday’s work is ideally asking for), so that being the case, the map.php modifications to PHP code we’ve made today, make it possible for (the much simpler) …

me copying (off the mapbox.com website, thanks, as part of the contents of a webpage) … then …
pasting that content within the functionality of our Google Chart Map Chart interface we host here as the PHP map.php‘s live run link

If you have the clipboard as your friend, your time around computers becomes so much more enjoyable, and flexible, and within your control. We, as programmers, need to think, on occasions, or encourage, on occasions, how the user is likely to use the clipboard, in conjunction with our applications. As you might surmise, that can be a pretty unpredictable “artform”.

Our PHP helper csv.php changed this way for today’s work.

Google Map Chart via URL Co-ordinates Tutorial

The last blog posting referring to the Google Chart Map Chart interface we host here was with Emoji Name Search Map Chart Weather Tutorial, but today we are presenting a major functionality addition with implications for other Google Chart interfacing PHP codesets here. We are allowing the user at the second prompt to take the data from a URL data source containing CSV (comma separated values) place,latitude,longitude data or those three fields in an HTML table element contents perhaps.

We’ve added the ability to “map” (tee hee) …

HTTP://www.rjmprogramming.com.au/PHP/Map/map.php?title=Where%20We%20Are&onclick=y&label=['Lat',&value='Lon',%20'Name']&data=,%20[-33.90743410270099,151.17646964910696,~Parent1~]%20,%20[-33.907440603083124,151.1764659419197,~Parent2~]

… could be a shortcut to that first URL same look. You can see another example using data from mapbox.com, thanks, show the scenario our tutorial picture illustrates.

The way this “mapping” (tee hee, tee hee) of URLs can happen is that the PHP supervisor map.php (changed this way and which you can try with this live run link) “includes” (ie. calls) …

include "../csv.php";

… a (now bigger, and more functional) csv.php (changed this way) does its best to handle a few looks to the CSV or tabular data, with code to allow for …

… am sure you’ll have noticed how bottom heavy it is on the “child” as far as functionality goes. What we like to call “the hard working duck syndrome”. Partly, that is because we see the Google Charts Map Chart interface we have as being a very useful “meeting point” with interfacing web applications tending towards the “where” of life.

Today’s job, extending yesterday’s Emoji Name Search Map Chart Tutorial is to add Map Chart interfacing to the great Weather Underground and its great API service for autocomplete name searches for weather (and hurricane) information … thanks.

The changes are again just to that “hard working duck” Map Chart interface “child” web application, as for yesterday’s work. We were very keen to do this, especially because …

Weather Underground database works most succinctly with Placename, Country identification pairs, better than for the …
Continent/Placename setup of (PHP) Timezones

… and so, while we are going to so much trouble scouring Timezone places for their associated Countries, it is a really good opportunity to slot in some Weather API interfacing to our Emoji World Flags web application, which is starting to be looking better and better as a trip planning aid.

We now have a three tier functionality hierarchy for our Emoji Flags of the World web application …

… all made so very possible when web applications sit in the same domain and you utilize the HTML iframe element.

We wanted to enhance its integration by …

adding in “locality pins” for all PHP Timezone places in the country of interest
involving Emoji flags in the Map Chart title (rather than as a pin) because Emojis, after all, are like textual data, not HTML (but can use HTML Entity representations in both)

To work the latter of these we called on recent experience with the “Fifth Beatle” discussion in Emoji Name Search Primer Tutorial …

We got quite excited recently with Rainbow Games PHP Emoji Tutorial when we added a (fourth Beatle) emoji helper, called Emoji Terra, into the mix of tools to gather emoji information. Today, we’ve got a new Emoji Search web application that introduces a new (fifth Beatle(?)) emoji helper tool to add into the “how we see it” mix …

We found that Emoji Terra could be used in our map Chart interfacing PHP to look up the HTML Decimal Entity for a flag of a country via the URL pattern …

HTTP://www.emojiterra.com/flag-for-[CountryNameSpacesMakeMinusSignsLowerCase]

So even though Google Chart Map Charts do not allow HTML in their titles there is nothing stopping you putting in an HTML Entity Emoji coding.

As far as the former goes, we again called on the PHP DateTimeZone class to scrutinize the first Timezone in the Map Chart title, derive its ISO 2 letter Country Code, and look through the array list of (PHP) Timezones to garner latitude and longitude, time now, and GMT offset information necessary to improve the “where” and “when” aspects of our Google Chart Map Chart interfacing.

Previous relevant Emoji Name Search Timezone Tutorial is shown below.

Emoji Name Search Timezone Tutorial

Yesterday’s Emoji Name Search Map Tutorial was a step in the direction of “where” functionality, but because PHP teams up with the supervisory HTML “Emoji World Flags” web application, to make all this happen, there is the opportunity to add interest by adding a “when” aspect to how it works.

As we’ve said many times now, should you have access to PHP, you also have access to its DateTimeZone class where Timezones can be linked to ISO 2 letter Country Codes, useful as an integration point as of recent times when we introduced ISO 2 letter Country Codes to today’s (supervisory) live run‘s world_flags.html HTML and Javascript code.

But it is not HTML code that changes today. It is its PHP partner emoticon_keyboard_shortcuts.php changed in this way, that arranges that its call of Google Charts Map Chart passes across a new URL …

&ccode=[ISO 2 letter Country Code]

… argument that uses a new PHP function as below (arrays shortened for practicality purposes) …

<?php function inctycodecheck($incd, $sofar) { $nearname=["Africa/Abidjan","Africa/Accra", ... ]; // array of Timezone names $retv=""; $retd=""; $otz = new DateTimeZone("UTC"); $jj=0; $origin_dt = new DateTime("now", $otz); for ($best1=0; $best1<sizeof($nearname); $best1++) { try { $tz = new DateTimeZone($nearname[$best1]); $cloc = $tz->getLocation(); $ctrycode = $cloc['country_code']; if (strtoupper($incd) == strtoupper($ctrycode)) { $remote_dt = new DateTime("now", $tz); $offset = ($tz->getOffset($remote_dt) - $otz->getOffset($origin_dt)) / 3600; $newp=$retd . $nearname[$best1] . "/" . $remote_dt->format('Y-m-d_H:i:s') . " (GMT" . $offset . ")"; $huhs=explode(" (GMT" . $offset .

… called later in the code with the new block of code as per …

<?php $urlis=urldecode($_GET['gmc']); // URL to point at template Google Chart Map Chart call for Country of interest if (strpos($urlis, ',,') !== false) { $urlis=str_replace(",,", urlencode($latis .

Yesterday’s Emoji Name Search Tailoring Tutorial was suitable for data sets of that smaller size able to be handled by the web server limit of URL length. But what if there are too many data items in your data set to be handled by PHP’s $_GET[] array URL ? and & delimited URLs? We, having PHP serverside code at our disposal, can turn to $_POST[] (HTML) method=POST form action=[here’sLookingAtYouKid] scenarios, to get around this issue. The unfortunate side effect of this is that the HTML mailto: a link (email client) method of sharing your Emoji web application relies on that $_GET[] approach, that is, unless you wrote a whole “bespoke” web application to help out, like we do today for our new Emoji “World Flags” web application with this live run, with this HTML and Javascript world_flags.html source code.

That new “supervisor” being a guinea pig idea into the $_POST[] thinking, we add some HTML form element input type=text additions to allow for, out of …

We think, perhaps, that emojis can be important for young “would be” programmers to launch into. Personally wonder how many “would be” programmers give the game up far too soon just because they don’t have those graphics skills, well, with emojis, a lot of that hard work, in miniature, has been done for you by some pretty creative people, so why not enjoy the fruits (chortle, in context, chortle) of their labour and start developing your own web applications to use them. Daily, their use is increasing, as are the sharing of access methods.

In today’s extension to the functionality started with yesterday’s Emoji Name Search Primer Tutorial we separate the Emoji Terra aspects to how it works and allow the user to …

perhaps supply a heading and subheading to describe the “concept” of that list
supply either a …

Emoji CSS performs similar functionality to Emojipedia, but has a pictorial view of Emoji names as well, right from the word go, thanks

Emoji Terra performs similar functionality as Iemoji but has a permalink organization more friendly to an “emoji search via emoji title” query, and that suits our purposes today, so, thanks a lot. Without this query by “emoji title” possibility we’d have been forced to adopt more of those “hardcoded” arrays, which would have been alright, but this second approach opens the door to “sport” events in “The Rainbow Games” web application using emojis of the future (ie. they haven’t been invented yet).

Again, in honour of “onions of the 4th dimension” approaches, we mainly, turn to the power of Javascript’s eval methodology to achieve this abstracted feeling to our web application. Today, with this, we go two thirds of the way along the “Mathematical Induction” approach …

prove for the first case
prove for the second case
prove for the n^th case

How does this use of Javascript eval manifest itself in this way?

there are two arrays that work with the “content” of our “Rainbow Games” sport(s) (well, at least, the first “sprint running” sport) called emoticons[] and choices[]
wherever we find references in the code to either of these two arrays we start to involve the global variable verbsuffix …
var verb='Sprint'; var verbs=['Sprint','Row']; var anotherverb='run'; var verbsuffix='';
… in altered ways like …
function plus(ih,ihep) { var outihep=ihep; if (eval("emoticons" + verbsuffix + "[" + ih + "]").indexOf('<p>') != -1) { outihep += ' (' + eval("emoticons" + verbsuffix + "[" + ih + "]").split('<p>')[1].split('<')[0] + ')'; } return outihep; }
… in that abstracted way … noting that sometimes you don’t need the “eval()” encasings …
and so, working through the code this way it just falls to the coder to define new members for all the arrays for all the new sports (ours is “rowing” today), some of those new arrays (like for rowing are emoticonsrowing[] and choicesrowing[]) to involve …
looking up emoji definitions from …
… not forgetting to …
make sure the event logics work for multiple sport scenarios … but mostly they do by sticking to the principles above … especially for the …
new HTML select (dropdown) element allows the user to pick a sport

Remaining a work in progress, you can try out our live run link that has underlying HTML and Javascript and CSS emoji_walk_animation.htm, and which changed in this way regarding today’s genericization work. We hope it gives you food for thought.

It’s been a while since we’ve written any conventional HTML and Javascript and CSS game. Today’s game uses the “emoticon” section of the Emoji character set, defaulting so far, to the “running woman” emoji featuring in Compound Emoji WordPress Usage Tutorial.

It’s the early days of our “Rainbow Games” web application, and we’re starting with the animation featuring horizontal hashtag navigation techniques for a running race start to our game. Where it finishes? Hard to say! Today, we’ve looked at “splits” and a finish line.
