I am using the following package to generate 3D Pie Chart: http://www.peters1.dk/webtools/php/lagkage.php?sprog=en
But this Chart doesn't have label or percentage over this graph. I would like to display "Denmark, US, Germany etc" over the corresponding graphs.. that will help to identify the percentage very easily.
Please help me or provide any package links which produce similar 3D Pie Chart
Have you tried Google Charts?
Have a look at http://code.google.com/apis/chart/ (free)
or http://www.anychart.com/products/anychart/gallery/Pie-and-Doughnut-Charts.php (costs, but very flexable)
Have a look at http://www.chartjs.org/, http://www.highcharts.com/https://google-developers.appspot.com/chart/interactive/docs/index both are pretty easy to integrate. ChartJs uses HTML 5 Canvas to create graphs and you can have 6 different chart types. Highchart is written in pure HTML5/JavaScript. All the best.
