<p class=MsoNormal><span style='font-family:Consolas'>Each letter represents a
person, and the entire map represents a state. Each person’s “risk
score” is a continuous numeric value, but I have categorized it into low,
moderate, and high for visual simplicity. What I’m hoping to do is draw
lines that will divide out the categories. The lines do not have to necessarily
be straight, but I would like them to be simple enough. I figure that I would
have to account for any overlapping or outlying persons. This is my initial
idea of how the map would turn out:<o:p></o:p></span></p>
