I've been using FourSquare's Swarm app to track my travels. I'd like to be able to plot the check-in locations on a Google Maps service (or any other web-based service outside of the Swarm App). I've had limited success so far (markers for only a handful of recent check-ins appear) using the Google Maps Javascript API and Foursquare's API.

There are several thousand check-ins over the last 6 years or so.

Is this possible, or does it exceed API usage limits?
