Visualizations - some formatting improvements

Use clearer labels for features rather than head_att. You don't want the reader to have to constantly cross-reference these.
- figure labels should have appropriate capitalization and no underscores
Figure 1 should have larger text and nicer labels.
Figure 2 is well chosen overall but should have clearer labels (size, and use Winner=Red/Blue rather than Blue Winner=0/1. Colour key should be categorical rather than a gradient (perhaps colour red for red wins, blue for blue wins?)
Table 2 is almost perfect - just list fewer significant digits!
Confusion matrix is excellent. All figures should be formatted like this!
