FlowingData explores how designers, statisticians, and computer scientists are using data to understand ourselves better – mainly through data visualization.

Data visualization lets non-experts make sense of it all.

The concept is pretty simple. Just like MapQuest, Google, Microsoft, and other mapping programs, Ride the City finds the shortest distance between two points. But there are two major differences. First, RTC excludes roads that aren’t meant for biking, like the BQE and the Queens Midtown tunnel. Second, RTC tries to locate routes that maximize the use of bike lanes and greenways.

The original idea was to build a web service designed to serve isochrone and isodistance polygons. The final purpose of the application, which is an implementation of the web service, is to display bakeries locations within isochrone (or isodistance) polygons, centered around a user-defined point. Users can then get the shortest path to one of the bakeries.

Renting an apartment in New York City is expensive, time-consuming, and chaotic. It’s our goal to fix these issues by creating a free listing service where the community has a voice and trustworthy brokers are rewarded. We’re building a set of tools so you can quickly assess a property by map, transportation routes, local interest information, pictures, and opinions shared by fellow apartment hunters. Since most of New York’s apartments can be found through a broker, it’s important that you connect with one you can trust. We’re giving the community a voice by asking them to share their views on individual listings and the brokers they’ve worked with so you can get a better understanding of what’s available.
