Using Foursquare's Venues API and Google's Maps API, I'm working on building a live heat map based on 4sq check-ins at venues in your area.
Want to know which bar is bumpin'? Check the map.
Looking for a place to eat and want to avoid the crowd? Check the map.
Want to see which city has the most sports fans? Check the map.
-Get an on-demand Google Maps overlay of the current Foursquare check-in activity in any area
-All venues are listed below, and you can click on any of the circles to get information about that venue
-Ability to search different locations (as well as using your current location via geolocation)
-Filter by venue category
-Filter by distance radius
-Fully client-side, so no waiting for server responses
-Color-coding for different tiers of activity
-Improved heatmap graphics
-User authentication to add their friends activity as an extra overlay
-Responsive web design for tablets/phones
