About this Viz
This type of visualization is called a small multiple and it allows us to see 24 snapshots in time in the same view. With a small mutliple, you can compare not only the two quarters immediately adjacent to each square, but also the same quarter for the previous and following years. Although there are many appropriate ways to display this data, the small multiple allows deep perspective that other options may not.
