Tangelo is a web framework built on top of CherryPy for producing rich web applications that pair your data with cutting-edge visual interfaces.

In a nutshell, Tangelo is a flexible HTML5 web server architecture that cleanly separates your web applications (pure Javascript, HTML, and CSS) and web services (pure Python), bundled with some great tools to get you started. Mix and match from the following to create your own breed:

• Bootstrap to put your app's style on a solid footing.
• D3 for constructing all manner of dynamic and animated charts.
• Vega, a brand new declarative language for defining visual interfaces.
• MongoDB for a flexible, speedy NoSQL backend to feed data to your apps.
• tangelo.js, a set of tools and interface elements that make it easy to create apps that put your data front and center.

See our documentation for a getting started guide and API descriptions.

Tangelo applications are divided into two functional layers: the frontend and backend, with Ajax bridging the gap between them.

The frontend is a standard website -- HTML for content and formatting, with CSS for styling and JavaScript for dynamic behavior. The JavaScript code can also make Ajax calls to the Python backend modules to request various services, such as database access, server side processing, or anything else that you can imagine.

See the Tangelo documentation for more information.

Fork our repository and do great things. At Kitware, we've been contributing to open-source software for 15 years and counting, and want to make Tangelo as useful to as many as possible.

Tangelo development is sponsored by the Air Force Research Laboratory and DARPA XDATA program.
