Tool for automatically generating and laying out an entity relationship diagram?
I am looking for some Windows software that can create relationship diagrams. I am not looking for the fancy kinds like Dia, etc., but rather something simpler where I can type in a bunch of items and specify links between them.
It should then create a picture of the relationships similar to the Google Wonderwheel or Visual Thesaurus. Preferably it will also support some kind of interactive map (like a Flash diagram that lets you pan, zoom, and rotate).
Finally, it would be great if it could support some stats and such like highlighting the most connected entity.
Oh, and it would be great if it could give “degrees of separation” chains between any given two entities.
