A nice use of data visualizations to get the point across (repeatedly). It's easy to cherry-pick the data and graph-type to demonstrate your point on one graph-- but to show the same trend on a number of different graph types, with a number of different data sources, over a variety of different periods-- well, that's harder to argue with.
