make it easier to see over- and under-representation

[deanmalmgren]

Even with the grey background and the white significance lines, its somewhat difficult to see which responses are over- or under-represented by the selected subgroup. Here are a couple of ideas about how we could do that:

I personally think I like Option C best; it is like you (i) align on the relative counts and then (ii) apply a filter on all of the redundant pieces of information in the visual. Like #28, it may be easier to do this if we switch to using <rect> elements instead of <path> elements. A couple of ways we could implement this functionality:

1. instantiate catcorr with instantiation options:

var cc = catcorr("#example", data, {display: 'relative'});

1. be able to toggle between the 'relative' and 'absolute' displays by incorporating a button into the legend. This might be best to address after (or while) improve legend functionality #27 is solved.

Option C got an upvote to help address this conversation on twitter with the how "confusing" the interface is.
