Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example.

I think it was in 2004 when I started investigating, learning the maths and testing all this stuff of projecting 3d points into a 2d plane...
Two years later, in 2006, I had a torus knot with flat shading with a light and a camera. Then Papervision3D came into the scene and I got distracted ;) GGobi data visualization system. Examples. This example demonstrates loading of CSV data, which is then quantized into a diverging color scale. The values are visualized as colored cells per day. Days are arranged into columns by week, then grouped by month and years. Chord diagrams show directed relationships among a group of entities.
This example also demonstrates simple interactivity by using mouseover filtering. Choropleth maps visualize geographic distributions using a color encoding. This diagram shows the distribution of age groups in the United States over the last 150 years. Unlike choropleth maps, cartograms encode data using area rather than color, resulting in distorted geographic boundaries. This simple force-directed graph shows character co-occurence in Les Misérables . A treemap recursively subdivides area into rectangles; the area of any node in the tree corresponds to its value. A sunburst is similar to the treemap, except it uses a radial layout. Gephi, an open source graph visualization and manipulation software.
