Glowing icons?

[LindseyWinn1]

Does anyone know how I could recreate this map (with my own data): http://images.huffingtonpost.com/2011-11-09-mcsparenesness0909.jpg

Is it a simple "create your own icon" or is it more complicated (mathematical, even?).

Thank you!

I won't say it's simple, but what you're talking about is feathering. It's basically accomplished with multiple buffers. See also http://www.esri.com/esri-news/arcwatch/1013/use-feathering-to-accentuate-the-area-of-interest-in-you...

It looks a bit more advanced than feathering to me. Maybe have a look in this direction

Actually here's an idea.

Create voronoi polygons around your point data them symbolise the resulting polygons using a circular Gradient Fill Symbol.
