{"version":"1.0","type":"rich","title":"Fork of Loading Data with React & D3","description":"This example displays a choropleth map of the UK's European Electoral Regions, rendered as shaded polygons with gray fills and teal borders on a blank canvas. It loads GeoJSON boundary data from a GitHub repository using `d3.json`, then projects the coordinates with `d3.geoMercator`. The map is drawn through `d3.geoPath` directly onto a Canvas context, with React managing the page structure but not the map’s state. The visualization demonstrates combining D3’s geographic utilities with a canvas-based rendering pipeline.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
