Color gradient dots. Two other
approaches are useful on small-scale
maps. One is to use a color gradient—
yellow through red, for example—to
depict the number of crimes at each
location. A yellow dot may be used to
represent places with a single crime, a
light orange dot may represent locations
with two crimes, and a deeper orange
dot might represent places with three
crimes. This approach has the advantage
of the use of graduated symbols but
overcomes the overlap problem.
