{"version":"1.0","type":"rich","title":"Missing Migrants Multiple Views with Brushing React Performance Optimization","description":"This visualization shows the geographic distribution and temporal trends of missing migrants worldwide, with a bubble map of incident locations and a linked date histogram for time-based filtering. Brushing the histogram filters the map’s circles in real time. Built with React and D3 v5, it uses `d3.geoNaturalEarth1` and `d3.geoPath` for map rendering, `d3.scaleSqrt` for bubble sizing, and `d3.brushX` for interactive selection, with `useMemo` and `useEffect` optimizing performance. Data comes from the Missing Migrants Project CSV.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/33b7625cb9e042eabe725176a95a4082?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
