Toxicity reloaded

This is a reimplementation of the Toxicity chart in JavaScript using D3.js.

Apologies for the hackneyed name. In my defence, though, you can load and reload this version of the chart in a browser.

Usage

• Download Checkstyle and copy the main JAR file into this directory
• Run Checkstyle on your Java source code (double-check the name of the JAR file)
  java -jar checkstyle.jar -c metrics.xml <source_dir> -f xml -o checkstyle_output.xml
• Open toxicity.html
• Load checkstyle_output.xml generated by Checkstyle
