Multiple graphics, multiple possible insights

One of my favorite mantras about visualization is that a single chart, graph, or map is unlikely to show everything you need to know about a story. It's through the combination of several adjacent graphics that compelling insights often arise.

NPR Visuals's latest project, “Maps Show A Dramatic Rise In Health Insurance Coverage Under ACA,” is a simple and lovely example of that principle: the choropleth map reveals geographic patterns; the histogram above it displays the decrease in the number of counties with high percentages of uninsured people.

The interactive visualization is followed by a story, some static graphs, and small multiple array of maps. They also are worth your attention.
