{"version":"1.0","type":"rich","title":"Another stab at a map","description":"This example shows a world map colored by fertility rate per country, using a blue-to-white linear scale to indicate values. The map is built with D3 v4, loading GeoJSON topology from a GitHub repository and CSV data from another source, then joining them by country name. It uses `d3.geoMercator` for projection and `d3.geoPath` to draw country boundaries as SVG paths. The color scale is created with `d3.scaleLinear` and applied to each country’s fill, rendering a choropleth visualization in a static SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2441a3a831145ce8764251767264e24?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
