Diagramming tool to depict objects

Question

I wanted to know what tools (preferably free) can be used to layout a collection of objects and their relationship - simple relationship like members referring each other, inheritance, attributes et.al. I would prefer a tool with which I can create and update the diagram as quickly as possible.

I'm not familiar with UML, but it's probably what I'm asking about.
