{"version":"1.0","type":"rich","title":"A9 World Map in D3","description":"This D3.js world map visualization displays the population density of countries using a blue color scale on a Natural Earth projection. The SVG-based choropleth map retrieves country boundary data from a Natural Earth GeoJSON file, while population statistics come from the CSV dataset loaded with `d3.csv`. The code uses `d3.geoPath` with `d3.geoNaturalEarth1` projection to render country shapes, and maps each country's population density value to the color scale, with gray indicating missing data. Hovering over a country reveals its name and density value through the SVG `title` element. The implementation includes `d3.scaleSequential` and `d3.interpolateBlues` for the color gradient.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/38deb6905c3149c1829f9f1df3fc5450?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
