Some time ago a visitor of SE site by the name of Uhl, who accidentally turned out a human factor engineer, pointed out some shortcomings of our rating bar graphs – extending left beyond the first score and disproportional lengths of bars relative to their values. He suggested a few variants which eliminate those drawbacks. We found the arguments are reasonable and corrected our bar graphs according to the recommendations.

Old rating bar design

New rating bar design

Thank you, Uhl, for your efforts; new bars are visually more correct and understandable indeed.
