Even when the shapes are disks it doesn't look right, because there is a
lot of green around them, the cells are rectangular. It would probably
be ok if the cells were squares but it'd require getting rid of the
runners and toolsets names as they're now. I wanted to avoid major
changes. Furthermore I'm not sure if that'd be really required. As I see
it, for non-regular cells what is important is the relation of a yellow
(failure) area and a green (pass) area in a cell. In other words how
much is the cell filled with "failures". I don't think it's ideal since
I agree that the regression matrix in general could have more modern
look. But I think that for now it'd be good enough.
