The Graph Gem

Example Multi-colored Graph

One of my favorite gems is Graph. At work we have a lot of data and graph makes it easy to see patterns and get the 10,000 foot view. The diagram is a visual representation of a several thousand line XML file. I used Nokogiri to extract the data and Graph to build the visual representation. I wrote about a hundred lines to generate the diagram, much of which is parsing the XML files and some additional CSV files.
