Online Diagram editor

What is it

This is a lightweight diagram editor that can work within a browser. It can be embedded in a web page and communicate with the surrounding application code.

The user can create Objects and their Relations, and associate with them custom application properties. The resulting diagram can be saved for further editing or exported in PNG format for presentation.

The developer can request the diagram structure in JavaScript to analyze it instantly, or save it on the server in a file or database. The diagram image can also be requested in JavaScript and saved on the server.

How does it work

The editor is a Java applet, which has several methods accessible in JavaScript, for example:

  var data = editor.getDiagram();
The diagram is represented as JSON structure which can be natively evaluated in JavaScript or parsed in PHP, ASP.NET, Java, Perl, C, Pascal, etc. The appropriate parsers can be found on JSON's website. Also, you can generate a diagram programmatically and open it in the editor.

Read the technical details in the developer's guide included in the download package.

System requirements

The editor requires Java 1.4 or later on the client's computer. Server environment (PHP, ASP, JSP, Python, Coldfusion ...) is insignificant since the editor is purely a client-side component.
Drag the icons to the canvas and use them as diagram Nodes.

Using the editor one can draw workflow chart, network diagram, website map, family tree, etc.
