Building on Mathematica's strengths in large-scale data handling, numerical optimization, and geometric computation, Version 6.0 brought a new level of automation to data visualization—with major new original algorithms for graph layout, immediate surface reconstruction, automated labeling, seamless handling of unstructured data, geometrically driven interpolation, and automatic date plotting—as well as major innovations in automated aesthetics.
ListPlot (modified) — multiple dataset support, plot markers, stems, etc.
ListLinePlot — plot lines through lists of points
ListPlot3D (modified) — now supports general irregular datasets, smoothing, etc.
ListPointPlot3D — 3D point scatter plot
ListSurfacePlot3D — surface reconstruction from 3D points
ListContourPlot3D — 3D contour surfaces from 3D field values
ArrayPlot (modified) — now supports symbolic values, sparse arrays, etc.
ReliefPlot — simulated topographic relief
DateListPlot — date and time plots
LayeredGraphPlot — draw a graph in a layered or hierarchical way
TreePlot — draw a tree structure
