Description

toscawidgets2 (tw2) aims to be a practical and useful widgets framework that helps people build interactive websites with compelling features, faster and easier. Widgets are re-usable web components that can include a template, server-side code and JavaScripts/CSS resources. The library aims to be: flexible, reliable, documented, performant, and as simple as possible.

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.custom, provides toscawidgets2 (tw2) widgets that render protovis data visualizations.
