Being able to create images from scratch is another really important aspect to look at for image manipulation. Not everything you'll do with image manipulation will be limited to working with photos. Frequently you'll want to provide some visual analysis of data, and PHP can build those images on demand.

We can start by creating a simple pie chart. Something easy to find is the global population distribution. In this example, we will create a pie chart with a very easy to adjust structure.

$data = array(

"Asia"=>4307107875,

"Africa" => 1037524058,

"Europe" => 816426346,

"North America" => 544620340,

"South America" => 400067694,

"Oceania" => 35426995,

"Antarctica" => 1169);

pieChartBuilder('./charts/pie-pop-dist.png', $data, 800, 600);
