This is a great visualization from the creator of Leaflet.js, the original lightweight web mapping library that gained significant traction over a decade ago. It is such a good visualization because it tells a compelling story that immediately highlights a couple of points that the author is trying to drive home in the article: namely it demonstrates quickly how bombings affect the daily lives of Ukrainians as well as quickly demonstrating the frequency and duration of which attacks occur and how attacks have increased in both frequency and duration in recent months.
