A while ago we highlighted a piece on Pro Publica about polluted air, where they did an impressive, hyper local analysis of pollution data across the US. This follow up article, about the methodological challenges in doing the research for that article, and about the lack of reliable official data, is just as interesting. It is an important reminder about the power that lies in not publishing data.

Visualisation

Every introduction to data visualisation includes Florence Nightingale's famous rose chart, it seems. But very few data journalistic pieces actually make use of spiral charts, radial charts, radar charts or anything in that chart family (and ever fewer manages to do it good enough to get away with it).
This one, from the New York Times, does a really good job, though, catching the omikron spread in light of the seasonal effect of covid-19:

Does data visualization have rules? Or is the answer to that question always “it depends”? Dataviz speaker and educator Nick Desbarats tries finding a middle ground in this article in the Nightingale journal, by codified some of that “it depends” gut feeling:

The 30 Day Map Challenge of November 2021 saw thousands and yet thousands of contributions, so we are grateful that Harry Wood of Open Streetmap picked a few (OSM related ones) worth a closer look in this blog post:
