Mathematica 9 adds major extensions for visualization. Legends are standard across visualization functions and are easily extended to custom graphics. Data with units can be plotted, with automatically determined labels. Gauges provide a new set of functions to display data or use as interface controls. Mathematica 9 also adds support for rendering volumes and hardware-supported antialiasing on Linux.
