I’m looking for a stand-alone Pie Chart which I can use in a GWT application. The Chart should be interactive, so that I can react on user input (read mouse clicks on the chart).
I’ve already looked at Google Chart Tools with GWT Visualization. This is exactly what I want. A simple to use PieChart class with user interaction and a simple and comprehensive data input. Except that the data is transfered to Google for the rendering part. The data should not leave the client or our server.
A colleague of mine found following library: GChart. Rather then using Flash we’ll try to draw our own. Not sure how easy this will be.
