The investigative site ProPublica published an investigation about the boom of video gambling in Illinois, which reveals the state’s bet on the industry did not yield the billions in tax revenue that were expected.

As always with ProPublica, the longform article includes an interesting mix of original photography, illustration, and data journalism. This time, it features an animated data visualization which points out the gap between the spread of video gambling locations and the state revenue they generated. I like how this map and this chart work together in an intuitive way.
