 # d3-zoom
 
-Pan and zoom SVG, HTML or Canvas using mouse or touch input.
+Panning and zooming are popular interaction techniques which let the user focus on a region of interest by restricting the view. It is easy to learn due to direct manipulation: click-and-drag to pan (translate), spin the wheel to zoom (scale), or use touch. Panning and zooming are widely used in web-based mapping, but can also be used with visualizations such as time-series and scatterplots.
 
+The zoom behavior implemented by d3-zoom is a convenient but flexible abstraction for enabling pan-and-zoom on [selections](https://github.com/d3/d3-selection). It handles a surprising variety of [input events](#api-reference ) and browser quirks. The zoom behavior is agnostic about the DOM, so you can use it with SVG, HTML or Canvas.

+
+The zoom behavior is also designed to work with [d3-scale](https://github.com/d3/d3-scale) and [d3-axis](https://github.com/d3/d3-axis); see [*transform*.rescaleX](#transform_rescaleX) and [*transform*.rescaleY](#transform_rescaleY). You can also restrict zooming using [*zoom*.scaleExtent](#zoom_scaleExtent) and panning using [*zoom*.translateExtent](#zoom_translateExtent).
+

+
+The zoom behavior can be controlled programmatically using [*zoom*.transform](#zoom_transform), allowing you to implement user interface controls which drive the display or to stage animated tours through your data. Smooth zoom transitions are based on [“Smooth and efficient zooming and panning”](http://www.win.tue.nl/~vanwijk/zoompan.pdf) by Jarke J. van Wijk and Wim A.A. Nuij.

 ## Installing
 
-If you use NPM, `npm install d3-zoom`. Otherwise, download the [latest release](https://github.com/d3/d3-zoom/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-zoom.v0.2.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_zoom` global is exported:
