Hi, I am currently trying to design a visualization for "Quality Indicator" (QI). The QI shall represent the quality of the data that has been loaded in to the software. I have a couple of preliminary thoughts -
1. A circle which shows a traffic light signal (red/yellow/green). This however would be a problem for the colorblind folks.
2. Signal bars - a set of 5 bars with increasing height (typically used in mobile phones to show the strength of the signal). Whether the bar is filled with a color depends on the quality of the input data.
