Data Vis Dispatch, December 6

The best of last week’s big and small data visualizations

Welcome back to the 71st edition of Data Vis Dispatch! Every week, we’ll be publishing a collection of the best small and large data visualizations we find, especially from news organizations — to celebrate data journalism, data visualization, simple charts, elaborate maps, and their creators.

Recurring topics this week include the U.S. Senate runoff election in Georgia, the eruption of Mauna Loa in Hawaii, the cost of living crisis, and the final days of the #30DayMapChallenge.
