+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:
+1. Deleted everything except for:
+* 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.
