Flowchart.js is a great tool for creating quick, simple flowcharts in a way that keeps you out of a WYSIWYG, and keeps your productive. No more drawing lines, no more determining how to draw a shape, no more deciding relative size and distance. Flowchart.js makes it easy to prototype new concepts and confirm product flows. Built in JavaScript, the library is complete with HTML rendering and a standard grammar and syntax for creating your flows.
