The purpose of this experiment is to see if a Visio-type of tool could be developed in a web browser. Using Prototype, script.aculo.us and Water Zorn's SVG library I managed to hack together a simple demo. It's not perfect, but it demonstrates that it can be done. There is no Ajax writeback to the server in this demo, but it could be easily added as a call in prototype.

Boxes You can resize boxes - select the box and grab a corner. You can also double-click on the title or description to edit it in-place.

Connectors Drop the green arrow from one box onto another.
