Finding customers in a market area

Finding customers in a market area

From Zoho, I'd like to be able to look at a map to find customers that are within a proximity of one another. example...pretend target stores are a customer and I need to see the store locations on a map for the Dallas/Ft Worth market. I think I can download  a zip code range and use the google fusion table to accomplish this.  I'm checking to see if Zoho has a function that would support this type of search.  Thank you.
