-Description:
-A JavaScript library for manipulating documents based on data.
-
-Subject to the security patch(es) described below, you MAY include d3 in web-facing content, such
-as in pages generated by bots or tools.
-
-
-Local Modifications:

-* d3.js         the standalone non-minified library
-* LICENSE       the BSD-style 3-Clause license
-* README.md     the readme file from github, for basic information
-
-2. Applied the following patches at the request of security:
-patches/001_no_html.patch        Disables the html() convenience functions, which could be used to
-                                 inject arbitrary content into the page. Instead of using html(),
-                                 programmatically create the individual nodes and/or text that you
-                                 require.
-                                 The html() methods have been modified to throw exceptions that
-                                 make it obvious that this feature is disabled for security.

D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation.
