Or only states. Or only ZIP codes. If you include names or addresses, it won't work, as each point would be tallied up individually. Eventually, by the way, I'm going to include support for 3-digit ZIP codes, which may be helpful for applications like this.

I'll take a look as soon as I have a minute. Thank you very much for letting me know. Looks like I completely missed that option! I’ll take a look as soon as I have a minute.

For instance, if you enable resizing by "n" and automatic frequency calculation, and your data looks like this: city,state New York,NY New York,NY Buffalo,NY ...it will draw the New York marker larger than the Buffalo one. However, if you really do have 1 million points in a particular location, and only a handful for others, it wouldn't be very useful, as the million-instance marker would swamp all of the others. It'd be better in that case to compile an Excel sheet (a pivot table, maybe?) that assigned a smaller range, say 1 through 5, to various exponential frequency "bins." For example, n=1 would represent 1-10, n=2 would be 11-100, n=3 would be 101-1000, etc. Then the map would be easier to read. That’s exactly what the data form can do, if you set it to “calculate frequency.” For instance, if you enable resizing by “n” and automatic frequency calculation, and your data looks like this:

city,state
New York,NY
New York,NY
Buffalo,NY

…it will draw the New York marker larger than the Buffalo one.

By scaling up, I mean if you have for example 2, 10, 100, 1000, 1 million, etc. points for a particular city (location), it would be great if that point could be larger (in proportion) to the others. So for example if the data included 1 million points to NYC, it would be great to see the NYC point larger than the others, preferably in proportion. Does that make more sense? And again, let me just re-iterate, for those of you who haven't checked out <a href="http://www.GPSVisualizer.com" rel="nofollow">GPSVisualizer.com</a> yet, you probably want to, it's got some great tools as you can see from the map I generated!
