{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example renders a world map using D3.js and TopoJSON. It draws country boundaries as SVG paths projected with a Mercator projection using `d3.geoMercator` and `d3.geoPath`. The map loads geographic data from the world-atlas countries-110m JSON file, converts TopoJSON to GeoJSON with the `feature` function, and appends each country path to the SVG. The visualization demonstrates a basic choropleth-free mapping workflow with styled countries and a blue sphere background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
