Do you know of any sample code showing how to draw a mind map using canvas?

I've se开发者_开发问答arched on the web for a code sample for creating a mind map using <canvas>. I've found that the infoVis toolkit samples use direct json for their mind map. I have a pre-constructed json and it will be a problem to convert it to the required format (id, children etc).

What I need is a way to convert a hierarchy of items into a map like visualization. Any help/ hint is appreciated

See if d3.js's sample gallery has anything that might help you:
