Fine-grained control of randomly entering and exiting things in D3.js, for impeccable object constancy. Adapted from an example co-authored with Mike Bostock.

An exploration of Mike Bostock's take on Ben Fry’s zipdecode, inspired by Nelson Minar’s reimplementation. This one uses deeply nested SVG elements and classes to target only the things that need to change.

Nesting the SVG made DOM creation bearable, but this is still too slow. Use Mike's canvas approach if you're looking for the "best" way to do this.

This animated bar chart is adapted from Mike Bostock's sample bar chart to allow redrawing and animated transitions.
