Part of this project is based on a real commercial software project and it builds statistics by data mining mostly XML Schema from a software system. Most of the XML Schema for this project was hand created and the rest comes from the open source Ruby programming language.
Ruby global variables are being used for the width and height of each chart.
I am using cloc, to display statistics about languages and lines of code at the top of the homepage.
On Ubuntu you can install cloc as seen below:
sudo apt-get install cloc
For Mac OS you can use Homebrew to install cloc:
brew install cloc
Fork and pull request. Simple.
