I have created a Web app using Google Fusion Tables, the Google Maps API and Derek Eder's Searchable Maps Template that allows someone to enter an address and distance, and then see which US Congressional Districts fall within the radius circle. A blind site visitor asked if it's possible to include a text list of those polygons that intersect with the radius circle. I thought that was a great idea and would like to help visually impaired users make use of the application.

Derek shows how to do a text list of points within the circle, but not intersecting polygons. Would anyone know how to modify this results list code to show intersecting polygons?

I was trying to play around with this code, but unfortunately I'm not very proficient in JavaScript (I use R to prepare all the data).
