6 . what is this?

The Circos table viewer uses the Circos application to turn data tables into chord diagrams.

into circularly composited visualizations like this

Through the settings panel You can control the manner in which your tabular data is parsed, filtered and displayed.

If you are interested in this approach, read Visualizing Tabular Data - Introduction. If you are interested in the details proceed to Visualizing Tabular Data - How to Use Circos to Visualize Tables.

This kind of plot is implemented in Pentaho and d3.js, which calls them chord diagrams. Circos table visualizations have been used to explore global migration (step-by-step tutorial) and inspired mosaic art.
