Why this chart?
A choropleth encodes one variable over geography; this series also splits by category, so the map carries a selector for it rather than collapsing the second dimension. It is a state-plus-national series, so the national total (the sum of the states) rides above the map as a KPI and trend, while the states carry the spatial breakdown.
Chosen: Choropleth map with a selector · auto-selected from the data profile.
Both downloads carry every observation — state, period, value, unit and source — and reconstruct the whole series.
