+
+[![](https://github-images.s3.amazonaws.com/skitch/Screen_Shot_2013-04-08_at_11.40.10_AM-20130408-114054.png)](http://bl.ocks.org/Caged/6476579)
+
+* [See a live demo](http://bl.ocks.org/Caged/6476579)
+* [Example code](/examples)
+
+### API Docs
+See the [API Documentation](docs/index.md)
+
+### Download Latest Version
+* [Development Version](https://raw.github.com/Caged/d3-tip/master/index.js) : **6kb** / **~2kb gzipped**
+
+### Install with NPM
+```
+npm install d3-tip
+```
+
+### Quick Usage
+```javascript
+/* Initialize tooltip */
+tip = d3.tip().attr('class', 'd3-tip').html(function(d) { return d; });
+
+/* Invoke the tip in the context of your visualization */
+vis.call(tip)
+
+vis.selectAll('rect')
+  .data(data)
+  .enter()
+  .append('rect')
+  .attr('width', function() { return x.rangeBand() })
+  .attr('height', function(d) { return h - y(d) })
+  .attr('y', function(d) { return y(d) })
+  .attr('x', function(d, i) { return x(i) })
+  .on('mouseover', tip.show)
+  .on('mouseout', tip.hide)
+```
+
+If you want basic styling, you can include `example-styles.css` using a service like
+rawgithub.com.

+# D3: Data-Driven Documents
+
+<a href="https://d3js.org"><img src="https://d3js.org/logo.svg" align="left" hspace="10" vspace="6"></a>
+
+**D3** (or **D3.js**) is a JavaScript library for visualizing data using web standards. D3 helps you bring data to life using SVG, Canvas and HTML. D3 combines powerful visualization and interaction techniques with a data-driven approach to DOM manipulation, giving you the full capabilities of modern browsers and the freedom to design the right visual interface for your data.
+
+## Resources
+
+* [API Reference](https://github.com/d3/d3/blob/master/API.md)
+* [Release Notes](https://github.com/d3/d3/releases)
+* [Gallery](https://github.com/d3/d3/wiki/Gallery)
+* [Examples](http://bl.ocks.org/mbostock)
+* [Wiki](https://github.com/d3/d3/wiki)
+
+## Installing
+
+If you use npm, `npm install d3`. Otherwise, download the [latest release](https://github.com/d3/d3/releases/latest). The released bundle supports anonymous AMD, CommonJS, and vanilla environments. You can load directly from [d3js.org](https://d3js.org), [CDNJS](https://cdnjs.com/libraries/d3), or [unpkg](https://unpkg.com/d3/). For example:
+
+```html
+<script src="https://d3js.org/d3.v4.js"></script>
+```
+
+For the minified version:
+
+```html
+<script src="https://d3js.org/d3.v4.min.js"></script>
+```
+
+You can also use the standalone D3 microlibraries. For example, [d3-selection](https://github.com/d3/d3-selection):
+
+```html
+<script src="https://d3js.org/d3-selection.v1.js"></script>
+```
+
+D3 is written using [ES2015 modules](http://www.2ality.com/2014/09/es6-modules-final.html). Create a [custom bundle using Rollup](http://bl.ocks.org/mbostock/bb09af4c39c79cffcde4), Webpack, or your preferred bundler. To import D3 into an ES2015 application, either import specific symbols from specific D3 modules:
+
+```js
+import {scaleLinear} from "d3-scale";
+```
+
+Or import everything into a namespace (here, `d3`):
+
+```js
+import * as d3 from "d3";
+```
