Everyone says data tells a story.
Most charts still bury it.

The rare ones that don't are what we go looking for in DataViz Weekly, our regular roundup of the data visualization projects we've found most interesting lately. We gather them from across the web, whether you build with data yourself or just enjoy seeing it done well. Here are the four in this edition:

▶️ Ancestry Across America

Patterns start to take shape across space.
Geographic data viz in practice 👇

We've spotted several interesting data maps out there over the past few days. So this edition of Weekly leans spatial. The four projects we selected show what maps can add when data has a geographic side.

Dots, bubbles, connectors, choropleths: each type fits a different kind of spatial question.
