First attempt at visualisation using Cmaps

This is a first attempt to write the [spreadsheet of terms](https://docs.google.com/spreadsheets/d/16pC2cDsdxlzv2CzlNMtStqt5-xHwDEsU6MjZVxWhrE4/edit?usp=sharing) using cmaps.

The cmaps graphs are available on the CMap Public server: [NI-O Map of Maps](http://cmapspublic.ihmc.us/rid=1MVC8PX65-13GSC4L-191G/Map_of_Maps.cmap).
