This is pretty cool, although it would be nice to see the different types of transportation across the same city. I see dramatic differences in the visualizations, sure, but they seem as dramatic as the differences in the layout and structure of these cities.

While I'm giving feedback, I must say I had to pause and re-read this sentence many times: "Human helps people move almost twice as much in six weeks". As I'm not familiar with the app, I went straight to that sentence and was baffled about some person who helps people change their place of residence a lot more for 6 weeks, but a lot more... compared to what? Took a while to arrive at "An app named 'Human' helps get people to move around more than they otherwise would within six weeks of beginning usage".
