How deeply does D3.js in Action, Third Edition cover transition?

Defines a 400-millisecond transform transition and explains the SVG-group workaround, but does not detail browser animation internals.

Transition

As explained in D3.js in Action, Third Edition

A CSS transition is a stylesheet-defined interpolation of an element's property values over time when those values change.

A CSS transition smoothly interpolates a changed property value over time. In a React visualization, it can animate label and badge positions by transitioning their CSS transform, avoiding more involved D3 animation code. section 8.7

Use the pattern when:

The element already moves through the CSS transform property. section 8.7
Many labels or badges need simple, performant movement. section 8.7
An SVG group should receive the transform for Safari compatibility. section 8.7

Animating labels

Assign the label group a class and update its inline transform as coordinates change: .label { transition: transform 400ms cubic-bezier(0.33, 1, 0.68, 1); } The browser then animates the label between its old and new positions. section 8.7
