An example of applying a scale transition to an entire SVG area, giving the impression of the graph growing into its final state.

Intriguing question from stackoverflow:

http://stackoverflow.com/questions/13662756/d3-js-passing-data-from-parent-to-child-nodes

This solution feels a little messy, since it goes into the dark details of d3.js - I'm only partially comforted by the fact that Mike Bostock's documentation, refers directly to use of __data__ and selection[0][0].

It also makes use of the 3rd function parameter, most usage of the data access function uses either 1 parameter (the data element) or 2 parameters (data element + index). But there is a 3rd parameter, through which d3 passes the current selection group index.

This 3rd function parameter - I recall reading about, but can't find the source. I would welcome being pointed at source material that documents its use!

Query from goolegroups: d3-js: subject: noob circle question.

Could not reproduce problem, so posted working index.html in the hope that it would shed light on the issue.

An example of attaching multiple visualisation components to the same source data.

Key history of this experiment:

• D3, the data driven visualisation enabler.
• Initial prototype written in handcrafted SVG with handcrafted data
