{"version":"1.0","type":"rich","title":"Fork of Let's make a map with D3.js!","description":"This example renders a choropleth-style map of continental Costa Rican cantons using a Mercator projection. It loads GeoJSON data via `d3.json` and draws the geographic features as SVG paths with `d3.geoPath` and `d3.geoMercator`. The code binds the fetched features to path elements, generating each shape’s outline directly from the GeoJSON geometry. The map uses a minimal styling approach with a full-window SVG and no additional data-encoding layers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/af56b883709b4f8589bdf46dc5f6a7e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
