Scientific and web visualization-graphics
Scientific visualization allows to represent graphically, 2 or 3D, information on geographic data, a scalar, vector or tensor. Open source softwares with appealing features are ParaView, Visit, MayaVi.
The same web technologies are allowing more and more rich and interactive views within the browser, for instance, HTML5 Canvas with WebGL, or JQuery, OpenLayers, GeoExt, Protovis, JSXgraph, Raphael, Flot, PhiloGL, Google Maps and Bing, among others.
