| 3 | **D3** is a small, free JavaScript library for manipulating HTML documents |
|---|
| 4 | based on data. D3 can help you quickly visualize your data as HTML or SVG, |
|---|
| 5 | handle interactivity, and incorporate smooth transitions and staged animations |
|---|
| 6 | into your pages. You can use D3 as a visualization framework (like Protovis), |
|---|
| 7 | or you can use it to build dynamic pages (like jQuery). |
|---|
| 8 | |

| 9 | ### Browser Support |
|---|
| 10 | |
|---|
| 11 | D3 should work on any browser, with minimal requirements such as JavaScript |
|---|
| 12 | and the [W3C DOM](http://www.w3.org/DOM/) API. By default D3 requires the |
|---|
| 13 | [Selectors API](http://www.w3.org/TR/selectors-api/) Level 1, but you can |
|---|
| 14 | preload [Sizzle](http://sizzlejs.com/) for compatibility with older browsers. |
|---|
| 15 | Some of the included D3 examples use additional browser features, such as |
|---|
| 16 | [SVG](http://www.w3.org/TR/SVG/) and [CSS3 |
|---|
| 17 | Transitions](http://www.w3.org/TR/css3-transitions/). These features are not |
|---|
| 18 | required to use D3, but are useful for visualization! D3 is not a |
|---|
| 19 | compatibility layer. The examples should work on Firefox, Chrome (Chromium), |
|---|
| 20 | Safari (WebKit), Opera and IE9. |
|---|
| 21 | |
|---|
| 22 | Note: Chrome has strict permissions for reading files out of the local file |
|---|
| 23 | system. Some examples use AJAX which works differently via HTTP instead of local |
|---|
| 24 | files. For the best experience, load the D3 examples from your own machine via |
|---|
| 25 | HTTP. Any static file web server will work; for example you can run Python's |
|---|
| 26 | built-in server: |
|---|
| 27 | |
|---|
| 28 | python -m SimpleHTTPServer 8888 |
|---|
| 29 | |
|---|
| 30 | Once this is running, go to: <http://localhost:8888/examples/> |
