13 Useful Javascript libraries for visualizations

As data visualization often needs to reach a broad audience the browser is becoming the number one tool to publish and share visualizations. A lot of visualizations require user-interaction to unleash their full potential, thus interactive applets that run directly in the browser are a a great way to analyze the data at hand. Beside the usual suspects like Flash, Silverlight and Processing, JavaScript is quickly gaining ground in the field of interactive visualization embedded in websites. We've collected 13 JavaScript visualization libraries that help you get started faster, keep it flexible and develop with higher reliability.

The code is light-weight, simple to learn and makes an ideal tool for visualizing data, creating user-interfaces and developing web-based games.
