D3 examples: visualise a nested hierarchy

From Mike Bostock's 'Zoomable Packing' D3 demo. This is a great way of visualising nested hierarchies. You can zoom in to get detail (in this case names relating to some programming paradigm of no importance to us) by clicking over any white object that you want to inspect. Zoom out again by clicking again.

You can imagine how a taxonomic hierarchy could be represented and explored in this way. We will soon be demonstrating examples that do just that. Read more about the relevance of data visualisation to Tomorrow's Biodiversity here.
