Data Vis Dispatch, November 18: Lunar missions, butterflies, and the #30DayMapChallenge
Welcome back to the 219th 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 recent lunar missions, the journeys of monarch butterflies, and the #30DayMapChallenge.
This Dispatch does not begin on Earth, but rather on the Moon, whose southern hemisphere has been particularly busy lately.
Back on Earth, many things are in flux. Billionaires are migrating, U.S. voter groups are shifting, and investments in semiconductors are being reorganized. Some of these flows are visualized in a particularly flowy way.
Another topic on the move: mobility. In some cities, it is easier to get around by bike or on foot than in others, as traffic has a major impact on how far you can travel. However, not all mobility projects are designed with civilians in mind; some are designed for the military.
The 2025 United Nations Climate Change Conference (COP 30) is still ongoing, as is engagement with climate issues. Of particular interest: how climate change is transforming the world, from opening new trade routes for China in the Arctic Ocean to creating dangerous glacial lakes in the Himalayas, and what climate investments are being made in green energy and on the African continent.
Other issues beyond climate investments have turned the spotlight on the African continent. These include its significant hydropower potential and different countries' opinions of each other.
Animals have been mapped and tracked: ball pythons from the southern Sahara have the potential to treat cardiac problems, chips attached to monarch butterflies reveal their incredible journeys to winter colonies in Mexico, and the United Kingdom is leading the race for the most popular dog breeds.
Whether we're buying furniture or breakfast, we may notice that prices are rising. The reason for this: inflation. One possible reason behind that reason: tariffs.
The older children get, the more time they spend on their mobile devices at school, using tools like ChatGPT, known for its prolific use of the em dash.
Shuffle, click, highlight, scroll — the following visualizations are full of entertaining interactions, even though their topics couldn't be more different: the ambiguous gender of Chinese names in the form of trees, trends in neuroscience publications as a heat map, and human remains in specimen jars.
Last but not least, our weekly highlights from the #30DayMapChallenge, in the following categories: 10-minute map, fire, cells, a new tool, and out of this world.
