{"version":"1.0","type":"rich","title":"world map","description":"This example visualizes the country of South Korea as a shaded map on a blank SVG canvas. It loads geographic data from the world-atlas TopoJSON dataset and uses the `topojson.feature` method to extract the country’s geometry. A `d3.geoMercator` projection fits the map to a 960×500 viewport via `fitSize`, and `d3.geoPath` renders the resulting polygon as a single dark path. The code demonstrates both external library imports via script tags and the basic D3 data-join pattern for drawing SVG shapes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
