Preface

Using ease


Transition can be thought of as a function of time. It is a function that maps time progression into numeric value progression, which then results in object motion (if the numeric value is used for positioning) or morphing (if the value is used to describe other visual attributes). Time always travels at a constant pace; in other words, time progression is uniform (unless you are doing visualization near a black hole, of course); however, the resulting value progression does not need to be uniform. Easing is a standard technique to provide flexibility and control to this kind of mapping. When a transition generates a uniform value progression, it is called linear easing. D3 provides support for different types of easing capabilities, and in this recipe, we will explore different built-in D3 easing functions, as well as how to implement custom easing functions with D3 transition.
