Protovis: JavaScript Visualization Library for Interactive Data Visualizations
Protovis is a Javascript visualization library that allows you to easily create interactive data visualizations for the web. It provides a declarative language for mapping data to graphical elements like bars, pies, lines, etc.
What is Protovis?
Protovis is an open-source Javascript visualization library released in 2009. It provides a declarative syntax to create a variety of interactive graphical displays like bar charts, scatter plots, pie charts, trees, networks and more.
Some key features of Protovis include:
- Simple declarative domain-specific language that allows you to bind data dynamically to graphical primitives
- Animated transitions between different visualization states
- Extensive range of scales for mapping data to visual properties
- Built-in support for interactions like tooltips, zooming, selections etc.
- Portability across browsers and devices
- Free open-source library under BSD license
Protovis fills a useful niche between full-featured visualization platforms like D3js and simple libraries that generate just one type of plot. The declarative language makes it easy to learn and fast way to create standard or custom data visualization on the web pages.
