Protovis

What is Protovis?

Protovis is a free and open-source visualization library that enables the creation of custom data views through a concise and flexible mark-based approach. Unlike low-level graphics libraries, Protovis simplifies the construction of visualizations by defining marks through dynamic properties that encode data, allowing for inheritance, scales, and layouts. The library utilizes JavaScript and SVG to deliver web-native visualizations that can be viewed in modern web browsers without the need for additional plugins. Although some programming experience is beneficial, Protovis is primarily declarative and designed to be learned through example-based exploration
