{"version":"1.0","type":"rich","title":"Missing Migrants on a Map with Fast Brushing Bars (V1)","description":"A world map uses semi-transparent circles to show the geographic distribution of missing migrants, with circle size encoding the total number dead or missing per location. A brushed time-series histogram below the map filters the displayed circles to a selected date range, updating the map dynamically. The visualization is built with React and D3 v5, using `geoNaturalEarth1` and `geoPath` for the map projection, `scaleSqrt` for circle sizing, and `brushX` for the interactive time filter. Data comes from a CSV of migrant incidents sourced from Simplemaps.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2285249b601a4232a08638d11fc328c6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
