{"version":"1.0","type":"rich","title":"covid -19","description":"This choropleth map visualizes COVID-19 deaths per million across 20 countries, with a red sequential color scale ranging from light to dark based on mortality rates. The map uses a Robinson projection via `d3.geoRobinson` and renders country boundaries as SVG paths through `d3.geoPath`, with a tooltip revealing the country name and death rate on hover. Geographic data comes from the world-atlas TopoJSON file, joined to the CSV dataset by ISO_A3 codes, and a linear gradient legend with an axis labels the color scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/67fdddbe795749e28bfcef898580a99a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
