# 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/>
