🌍 #30DayMapChallenge Day 24: Only circular shapes Inspired by @bjnnowak.bsky.social work, today's map visualizes displacement across Africa in 2024. Each bubble is split to contrast those displaced within a country with those who have sought refuge there. Code: shorturl.at/TZMkZ #maps #rstats

A bubble map of African countries displaying displacement data for 2024. Each bubble is split into two halves: one representing internally displaced people (IDPs) and the other representing refugees hosted within the country. Bubble sizes vary by the total displacement numbers, illustrating the relative scale of each country's displacement challenges. Yellow indicates IDPs (on the left side of each bubble), and blue represents refugees (on the right).
