Loading github project into wordpress plugin

Question

I am trying to use the following github project in my wordpress plugin:

PHP Object wrapper for the Google Chart API

I tried the following:

 require_once(WPPLUGIN_PATH. "gchart/gChartInit.php");

 $piChart = new gPieChart(); // <---- here I get the error

 $piChart->addDataSet(array(112,315,66,40));
 $piChart->setLabels(array("first", "second", "third","fourth"));
 $piChart->setLegend(array("first", "second", "third","fourth"));
 $piChart->setColors(array("ff3344", "11ff11", "22aacc", "3333aa"));
 echo $piChart->getImgCode();

My problem seems to be that when I am using the above code, it jumps at line $piChart = new gPieChart(); into another wordpress-plugins autoloader and does not load the gPieChart.php properly.

The error message is:

[26-Jul-2016 20:39:59 UTC] PHP Fatal error:  Class 'gPieChart' not found in /home/ubuntu/workspace/wp-content/plugins/wp-analytics-mail/sendTestMail.php on line 267

Any suggestions how to make the above code work?

I appreciate your reply!

Here's what you do.

Install Composer as per the doc or, if you're on Windows/Unix, figure out how to install the thing in your environment.
Create new file called composer.json in the root folder of your plugin (in this case wp-analytics-mail)
Again, as per the doc, paste this into the composer.json

{ "require": { "gchartphp/gchartphp": "dev-master" } }

In the command line, get to the plugin folder and run composer update
Put require 'vendor/autoload.php'; somewhere close to the top of your main plugin file (sendTestMail.php)
Lower down in the same file, initialize and use the library:

$piChart = new gchart\gPieChart();
