Popularity of genres today, based on how many Google Play Music users have those artists or albums in their libraries. It takes a second to wrap your head around the temporal aspects of it – it’s basically looking at music that is in most people’s playlists now and telling you when it was made. It’s hard to tell if this is thus revealed preference of how good each genre was at each time, how popular, how enduring, or how old people are (whose music collections go back further?). Ok, I’m not sure exactly what this means. Haha!

Each stripe on the graph represents a genre; the thickness of the stripe tells you roughly the popularity of music released in a given year in that genre. (For example, the "jazz" stripe is thick in the 1950s since many users’ libraries contain jazz albums released in the ’50s.) Click on the stripes to zoom into more specialized genres.

The creator asked 30 people to draw a map of the world and then combined the results. Pretty sad. (the bottom image – it’s a mockup, not an exact replica of the real result)

The original drawings are even more pathetic, for the most part:

Home equity vs mortgage debt is about to flip back to the good side.

Of course, this is on a net basis, so a lot of people are still underwater – 6.3 million according to one estimate (13% of mortgages).

This map is missing a proper label for the legend (sigh) but it is apparently “concentration of underwater mortgages”.
