Mapping business data
Atlanta Regional Sales Map

This is an anonymized version of a map I created for a client, intended to measure certain charateristics of the Atlanta market relevant to one of their products. At the client's request, I have changed the key and some of the labels on this map, in order to prevent the disclosure of potentially proprietary business information.

Fake transit maps
Hypothetical Tampa Bay Rail Transit Map

The Tampa Bay region is home to 2 to 3 million people, yet it has no rail transit options whatsoever. This map imagines what a functional rail system might look like there.

Home Values and Sinkhole Location in Tampa Bay

Tampa Bay is a hot-spot for sinkhole formation. Do local home values adequately capture the potential cost of sinkhole damage? This map was part of a research project intended to answer that question; it was published in "Florida Geographer" in 2007.

Iowa River Recreation Map

The client was a non-profit organization whose mission was to promote Iowa's rivers and waterways for recreational purposes. I used Raphael.js instead of D3.js for this project, and in the process figured out how to bind data to objects in Raphael, which is not something that library is designed for.

Linguistic Isolation in New Bedford, MA

This map plots the relationship between concentrations of foreign-born residents and linguistic isolation in the city of New Bedford, Massachusetts. The percentage of foreign-born residents in each Census tract is reflected in the tract's fill color. Each tract's outline color will change when you mouse over it; the color represents the percentage of foreign-born residents who speak English "not well" or "not at all".

The relationship between declining population and rising homicide rates

It's conventional wisdom that Detroit's high crime rates were what drove the city's rapid "white flight" in the 1960s and 1970s. But is that true? Which came first - falling population or rising crime rates? And how did this play out for other American cities?

Histogram of population density changes in Detroit, MI (1970-2010)

This chart plots population density change in the Detroit metro area in a non-geospatial way. It can be hard to fully grasp just how many Census tracts lost significant amounts of people when you're reading a map that covers such a large area.
