+# D3
+
+**D3** is a small, free JavaScript library for manipulating HTML documents
+based on data. D3 can help you quickly visualize your data as HTML or SVG,
+handle interactivity, and incorporate smooth transitions and staged animations
+into your pages. You can use D3 as a visualization framework (like Protovis),
+or you can use it to build dynamic pages (like jQuery).
+
+### Browser Support
+
+D3 should work on any browser, with minimal requirements such as JavaScript
+and the [W3C DOM](http://www.w3.org/DOM/) API. By default D3 requires the
+[Selectors API](http://www.w3.org/TR/selectors-api/) Level 1, but you can
+preload [Sizzle](http://sizzlejs.com/) for compatibility with older browsers.
+Some of the included D3 examples use additional browser features, such as
+[SVG](http://www.w3.org/TR/SVG/) and [CSS3
+Transitions](http://www.w3.org/TR/css3-transitions/). These features are not
+required to use D3, but are useful for visualization! D3 is not a
+compatibility layer. The examples should work on Firefox, Chrome (Chromium),
+Safari (WebKit), Opera and IE9.
+
+Note: Chrome has strict permissions for reading files out of the local file
+system. Some examples use AJAX which works differently via HTTP instead of local
+files. For the best experience, load the D3 examples from your own machine via
+HTTP. Any static file web server will work; for example you can run Python's
+built-in server:
+
+ python -m SimpleHTTPServer 8888
+
+Once this is running, go to: <http://localhost:8888/examples/>
+
+### Development Setup
+
+This repository should work out of the box if you just want to create new
+visualizations using D3. On the other hand, if you want to extend D3 with new
+features, fix bugs, or run tests, you'll need to install a few more things.
+
+D3's test framework uses [Vows](http://vowsjs.org), which depends on
+[Node.js](http://nodejs.org/) and [NPM](http://npmjs.org/). If you are
+developing on Mac OS X, an easy way to install Node and NPM is using
+[Homebrew](http://mxcl.github.com/homebrew/):
+
+ brew install node
+ brew install npm
+
+Next, from the root directory of this repository, install D3's dependencies:
+
+ make install
+
+You can see the list of dependencies in package.json. NPM will install the
+packages in the node_modules directory.
