{"version":"1.0","type":"rich","title":"Fork of GeoVisualization - Choropleth map of the world","description":"This example shows a choropleth map of the world coloring each country by population, with a blue threshold color scale. It uses `d3.geoPath` and `d3.geoMercator` to project and draw country boundaries from a GeoJSON file, while population data is loaded from a CSV and mapped by country code. Mouseover transitions dim all countries except the hovered one, which gains a black stroke. The visualization is built with D3 v6 and rendered as SVG, using `d3.scaleThreshold` and `d3.schemeBlues[7]` for the color encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c94e75cb587455e8b60817e02e5c0c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
