Automatic label placement ideas?

[Daniel]

I posted a question over here about scatter chart label placement:
http://stackoverflow.com/questions/5833695/bubble-chart-label-placement-algorithm-preferably-in-javascript

It would be great to see some sort of label placement algorithm/helper
as part of D3 but maybe this is far outside the scope?

I tried creating my own "label placer" using the SVG
getIntersectionList method (just iteratively moving the labels until
they no longer overlap), but the getIntersectionList method does not
seem to be implemented in Firefox etc. (and probably it wasn't a very
good approach anyway ...)

If you have any thoughts on this, I'd be interested to hear :)
