TinyMCE Editor

You can use a plugin for TinyMCE Editor to add UML into your editor.

Demo

First, let's start by a working example:

You can click on "UML" button in the toolbar to add a new diagram. You can also select an image, and click on this same button to edit the diagram. <img style="display: block; margin-left: auto; margin-right: auto;" src="http://www.plantuml.com/plantuml/img/SyfFKj2rKt3CoKnE1G00" alt="Bob -> Alice" /> You can also select a text diagram, and then click on "UML" button to generate the diagram: @startuml class Foo @enduml Very easy to used and to integrate.
