mousewheel-zoom + click-to-center

[jason69]

Hello,

Would it be possible to implement a mousewheel-zoom + click-to-center like offered by d3: http://bl.ocks.org/mbostock/2206340

The best would be something like in google maps : the more you zoom, the more data is accurate. I mean each time you zoom, you retrieve data (e.g. in json) according to the current level of zoom and time interval.

This feature is very interesting when large amount of data is available but cannot be displayed entirely for performance reasons.

I'm not good coder, but I would be happy to help if needed. I just need some start point and clues...

BTW: very nice library! I love it :-)
