{"version":"1.0","type":"rich","title":"A D3 map","description":"This visualization combines a D3 natural Earth projection map with a time-series histogram. The map displays circles sized by migrant death tolls using `geoNaturalEarth1` and `geoPath`, while the histogram bins reported dates into monthly intervals using `d3.histogram` and `scaleTime`. The React app loads country boundaries from World Atlas TopoJSON and migrant data from a CSV, rendering all elements as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1f33966ad5a544b9a429f9ee6c36fd05?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
