visualization - Does anyone have a handy visulization widget that I can use for a web project? -

-

what want lots of nodes can expand making mind map.

i'd ideally expand , collapse nodes. able navigate either dragging around page, or following expanded nodes.

i have colleague needed kind of functionalities graph maven dependencies between projects. ended using freemind visualization. had write xml file conforming freemind format. think can use opml file format , find ready use xslt transform freemind format. maybe freemind supports opml directly (i havent used long time).

once have data in freemind, can either export them, or use freemind applet display interactive mindmap on website.
