In interpreting and illustrating events taking place in some locations and
not others, the use of shaded or "color-contrasted" maps can be useful. This
webform allows you to choose up to twelve different groupings of states - along
with your title, choice of colors and labels. An application will then
draw a US map (as a "gif" format file) with your groupings shown in the
selected colors. The map can then either be printed or saved and used later.
