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.

Installation is simple -- just install a few dependencies, clone this repository, build the system, and run the tangelo start command. Then, point your browser to http://localhost:8080 to check things out.

See the Installation page on the wiki for detailed instructions.

Tangelo applications are divided into two functional layers: the frontend and backend, with [Ajax](http://en.wikipedia.org/wiki/Ajax\_(programming\)) 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 Application Architecture page on the wiki 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.
