{"version":"1.0","type":"rich","title":"map-sumpapers","description":"This map visualizes the sum of academic papers per country from 1960 to 2019, with countries colored along a purple sequential scale and hover tooltips showing exact counts. It uses `d3.geoNaturalEarth1` and `d3.geoPath` to render world countries from a TopoJSON atlas, while a CSV file supplies paper counts keyed by country code. The legend, built with `d3.scaleOrdinal`, lists binned ranges, and `d3.zoom` enables panning and scaling. Color assignment relies on a custom `colorData` function using `d3.schemePurples`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f371d76c55a4be7951a121ee245d31d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
