This color chart by Pew Research published 10 September 2020, reveals a useful way to depict split opinions of a study. Here are a few observations:
1. Color coding the groups makes it easy to detect the differences.
2. Limiting the chart to 4 items makes it easy to see what's going on. If there were more items, a separate chart and text would be better.
3. The anchor points along a line provide visual evidence of the divide.
4. The "All voters" column on the right shows how useless an average would be to understand what is going on in a society (in this case, the US).
