{"version":"1.0","type":"rich","title":"Volcano Map","description":"This visualization displays the global distribution of historically significant individuals from the Pantheon dataset, where each circle represents a person positioned by birth location. The map uses equal-area natural Earth projection with graticule lines, and circle size encodes the Historical Popularity Index (HPI) using a square-root scale. The accompanying date histogram enables time-brushing to filter the map through linked selection. Built with React, the implementation leverages D3 modules including `geoNaturalEarth1`, `geoPath`, `scaleSqrt`, and `scaleTime`, while tooltips employ the Tippy library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0a3b5853316d46cf938962c17c282edb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
