-for the Web. It is pretty, interactive, and fast.
+`protovis`_ composes custom views of data with simple marks such as bars and dots. 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.
This module, tw2.protovis, provides `toscawidgets2 (tw2)`_ widgets that render `protovis`_ data visualizations.
