I think I see what's happening. The class is displaying the png direct -
it sends a header of 'Content-type: image/png'. I think you are trying
to insert it in a page where you've already sent a header.
Try changing one of the last lines in the piegraph class code from:
imagepng($final);
To:
imagepng($final, "test.png");
Then create a regular <img src="test.png">.
