A scatter plot represents observations as points positioned by two variables. It helps reveal patterns, differences, and unusual values before drawing more specific conclusions. section 3.3.4 section 3.3
For delivery analysis, place customer states on one axis and seller states on the other. Color each point by delivery time so regional differences become visible. section 3.3.4
Make the resulting chart easier to inspect:
- Use a logarithmic color scale when low values dominate and high-value outliers flatten the rest of the color range. section 3.3.4
- Sort categorical axis values consistently so related state pairs are easier to find. section 3.3.4
