This may be a tool to add to your toolkits. I'm thinking particularly about folks doing school rankings, since that's what the rather informative video included with the article demonstrates. ;-)
According to:
http://phys.org/news/2014-01-open-source-lineup-software-enables-granular.html"To shed light on the trustworthiness of rankings, Harvard researchers have created LineUp, an open-source application that empowers ordinary citizens to make quick, easy judgments about rankings based on multiple attributes."
"LineUp is part of a larger software package called Caleydo, an open-source visualization framework developed at Harvard, Johannes Kepler University, and Graz University of Technology. Caleydo visualizes genetic data and biological pathways—for example, to analyze and characterize cancer subtypes."
