The standard deviation "ribbon" should be replaced with posts #29

The code to do this is actually probably buried in a previous commit.

Also, one idea is to have "stacked" bars, in a sense. For each group, a light grey bar raises to the minimum variation level for all groups. On top of that, a darker bar rises to the level of variation for that group.

Both are solved in commit 1e98eccfb5f5f46ed5db948259fc72f203c5da4c

From Bob Pruzek

Here, I'd do something like this: Use only one color (maybe a shade of grey between your light and dark), and do not attempt to compare each with just the smallest s.d.; rather i. stop w/ just that simple change, or ii. place two thin horizontal (grey?) lines so that the bottom serves as a floor for all bars, and the top one represents the square root of the average within group variance (not quite the average s.d.). The advantage of ii. should be obvious... and your ideas stimulated this.
