{"version":"1.0","type":"rich","title":"D3 Course - Missing Migrants, Multiple Views","description":"This interactive visualization combines a natural Earth projection world map with a time-series histogram to explore the Missing Migrants Dataset. The map displays each migrant event as a semi-transparent circle scaled by total dead and missing using `d3.scaleSqrt`, while the histogram aggregates monthly deaths using `d3.histogram` and `d3.sum`. A brush on the histogram, implemented with `d3.brushX`, filters the map’s displayed events based on the selected date range, linking the two views. The code uses `d3.geoNaturalEarth1` and `d3.geoPath` for map rendering, with country boundaries from World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9d58512085d9499697d49dd96d0e926a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
