Rappid is now JointJS+

JointJS+ (formerly known as Rappid) can be used to create advanced visual tools in days, not months. Whether you're looking to develop a workflow editor, modeling tool, a designer or a monitoring application, JointJS+ speeds up your development significantly by providing all the necessary user interface components. It takes the best of HTML5 and SVG to give you the right tools for building your web products. It operates completely client-side and is therefore independent of your backend technology.
