Inequality and New York’s subway

This is the link to the data visualization that I commented in class last week: http://www.newyorker.com/sandbox/business/subway.html

It shows graphs for each New York subway line and each graph shows the median household incomes of the populations living near subway stations on that line.

In our class discussion we came to the conclusion that people from New York who visit the URL will most likely click on the subway line that they normally take. We therefore wondered whether other ways of presenting the data would have been more comprehensive for a user interested in inequality in New York City.
