Fivethirtyeight.com has a roundup of interesting visualizations they did in 2020. There’s a lot here, but one theme I think I would like to try to make use of is is pretty simple. When you are counting something, put the count in context by first showing a bunch of empty squares that represent the potential or total number of something (voters, or citizens stopped by police, or human beings with potential Covid exposure). Then put dots in some of the boxes, or color in some of the boxes, to illustrate the count. If you want to introduce some additional categories, you can use colors or put boxes around the boxes, or to get really fancy, put groups of boxes on a map. This technique undoubtedly has a name, but the article doesn’t tell me what the name is.
