Vizualistics: Your entire Foursquare history charted and graphed

Each time we check in on Foursquare, we’re adding data points Foursquare uses to calculate popular venues and learn our habits, but why should they be the only ones who get to take advantage of all that data? Thanks to Foursquare’s API, we each have access to our own data to perform calculations on our own habits. Vizualistics, a new online tool, makes it easy to tease that information from Foursquare’s API and chart and graph your own data to your heart’s content.

By default, Vizualistics presents, for example, a stacked bar chart of your check-ins over the past 12 months broken down by category. It also presents bar graphs showing your check-in volume across popular categories like bars, restaurants, coffee shops and the gym.

Its real power, though, lies in the ability to create custom stats based on categories and time limits you choose. I used it to compare a graph of my burrito consumption since I joined Foursquare to a graph of gym visits and learned that — despite what my waistline shows — the burritos are on the decline while the gym is on the rise.

The ability to quantify my own actions through check-ins is one of the primary reasons I enjoy using Foursquare. Vizualistics’ charts and graphs make that easy to do in a customizable way and then share that data with friends.
