  "readme": "# d3-ease\n\n*Easing* is a method of distorting time to control apparent motion in animation. It is most commonly used for [slow-in, slow-out](https://en.wikipedia.org/wiki/12_basic_principles_of_animation#Slow_In_and_Slow_Out). By easing time, [animated transitions](https://github.com/d3/d3-transition) are smoother and exhibit more plausible motion.\n\nThe easing types in this module implement the [ease method](#ease_ease), which takes a normalized time *t* and returns the corresponding “eased” time *tʹ*. Both the normalized time and the eased time are typically in the range [0,1], where 0 represents the start of the animation and 1 represents the end; some easing types, such as [elastic](#easeElastic), may return eased times slightly outside this range. A good easing type should return 0 if *t* = 0 and 1 if *t* = 1. See the [easing explorer](http://bl.ocks.org/mbostock/248bac3b8e354a9103c4) for a visual demonstration.\n\nThese easing types are largely based on work by [Robert Penner](http://robertpenner.com/easing/).\n\n## Installing\n\nIf you use NPM, `npm install d3-ease`. Otherwise, download the [latest release](https://github.com/d3/d3-ease/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-ease.v1.min.js) or as part of [D3 4.0](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported:\n\n```html\n<script src=\"https://d3js.org/d3-ease.v1.min.js\"></script>\n<script>\n\nvar ease = d3.easeCubic;\n\n</script>\n```\n\n[Try d3-ease in your browser.](https://tonicdev.com/npm/d3-ease)\n\n## API Reference\n\n<a name=\"_ease\" href=\"#_ease\">#</a> <i>ease</i>(<i>t</i>)\n\nGiven the specified normalized time *t*, typically in the range [0,1], returns the “eased” time *tʹ*, also typically in [0,1]. 0 represents the start of the animation and 1 represents the end. A good implementation returns 0 if *t* = 0 and 1 if *t* = 1. See the [easing explorer](http://bl.ocks.org/mbostock/248bac3b8e354a9103c4) for a visual demonstration. For example, to apply [cubic](#easeCubic) easing:\n\n```js\nvar te = d3.easeCubic(t);\n```\n\nSimilarly, to apply custom [elastic](#easeElastic) easing:\n\n```js\n// Before the animation starts, create your easing function.\nvar customElastic = d3.easeElastic.period(0.4);\n\n// During the animation, apply the easing function.\nvar te = customElastic(t);\n```\n\n<a name=\"easeLinear\" href=\"#easeLinear\">#</a> d3.<b>easeLinear</b>(<i>t</i>) [<>](https://github.com/d3/d3-ease/blob/master/src/linear.js \"Source\")\n\nLinear easing; the identity function; *linear*(*t*) returns *t*.\n\n[<img src=\"https://raw.githubusercontent.com/d3/d3-ease/master/img/linear.png\" alt=\"linear\" width=\"100%\" height=\"240\">](http://bl.ocks.org/mbostock/248bac3b8e354a9103c4/#linear)\n\n<a name=\"easePolyIn\" href=\"#easePolyIn\">#</a> d3.<b>easePolyIn</b>(<i>t</i>) [<>](https://github.com/d3/d3-ease/blob/master/src/poly.js#L3 \"Source\")\n\nPolynomial easing; raises *t* to the specified [exponent](#poly_exponent).
