{"version":"1.0","type":"rich","title":"Untitled","description":"This example visualizes six French cities on a Mercator map, encoding each location with a circle whose size corresponds to a numeric value and whose fill pattern distinguishes three categorical groups (A, B, C). The map uses `d3.geoMercator` and `d3.geoPath` to project and draw France from a GeoJSON source, while the textures library generates distinct striped patterns via `textures.lines()` for each group. Circles are positioned with the projection, sized via `d3.scaleLinear`, and styled with dashed black strokes and transparent fills to emphasize the pattern overlays.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4489dce36d004e76886e27383d100922?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
