{"version":"1.0","type":"rich","title":"Fork of Let's make a map with D3.js!","description":"This example builds a choropleth-style world map using D3.js v5, displaying country boundaries from the world-atlas TopoJSON dataset. The visualization renders the map as SVG paths, with countries filled in light green and a blue sphere for the background. It uses `d3.geoPath` with a `geoNaturalEarth1` projection to project the geographical data, while `topojson.feature` extracts the country geometries. Population data from a CSV file is loaded, though the code only logs country data to the console rather than encoding values visually, and includes a hover effect that turns countries red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ddae042bddba413e84cb9f5852e989ba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
