Diagram

Overview

The DevExtreme JavaScript Diagram provides a visual interface to be used when you design new diagrams or modify existing ones. This control is available as a jQuery plugin and can be bound to external data. The Diagram provides more than 40 resizable shapes, which you can drag and drop onto a page. Shapes and connectors are highly customizable.
