How to make JpGraph graph look nice?

I’ve never used JpGraph but I keep hearing good things about it. So, I gave it a try, followed this JpGraph tutorial but the results came rather… dull. How can I add some grace and style to the pix? Or should I try some other library?

require_once ('jpgraph.php');
require_once ('jpgraph_pie.php');
require_once ('jpgraph_pie3d.php');

  // Browser usage statistics, %
  $data = array(29, 21, 18, 18, 4, 10);
  $legends = array(

  // Creating a new graphic
  $graph = new PieGraph(600, 450);

  // Naming the graphic
  $graph->title->Set('Browser usage statistics');
  $graph->title->SetFont(FF_VERDANA, FS_BOLD, 14);

  // Legend positioning (%/100)
  $graph->legend->Pos(0.1, 0.2);

  // Creating a 3D pie graphic
  $p1 = new PiePlot3d($data);

  // Setting the graphic center (%/100)
  $p1->SetCenter(0.45, 0.5);

  // Setting the ancle

  // Choosing the type
  $p1->value->SetFont(FF_ARIAL, FS_NORMAL, 12);

  // Setting legends for graphic segments

  // Adding the diagram to the graphic
