Online chart editor

Question

I love to use Google Documents as MS Word and MS Excel replacements for online collaboration.

However, now I need to discuss architecture layout for my software. Nothing too fancy, perhaps a little (pseudo-)UML, but mostly basic shapes (rectangles, ellipses etc.) with labels, connected by thin lines or arrows.

In olden Windows times I'd go for Visio, and be happy. But now I want to use online tool.

Preferably free. No need for code reverse engineering etc., just plain assisted vector drawing.

Any advice? What do you use?

Answer 1

Gliffy and Cumulate Draw look promising.
