I'd like to display an array of various location points, that share the same group. I've been tasked with designing a visual UI that houses a Bing Maps screen and displays several (location based - geocoordinates) map pins according to their group. I originally thought each pin should be connected via a line (like a web) to illustrate their relation and literally "connect" them or group them together. Each group would be differentiated by color.
This idea is feasible, however, when rendered it just looks messy. So many lines! I also thought about just coloring the pins the same, but it's a bit too difficult to see their relation.
Any ideas would be very very appreciated. Thanks!
