{"version":"1.0","type":"rich","title":"World Map Visualization","description":"A world map visualization colors each country according to a numeric value from an external CSV dataset. The example uses D3 v6 with a Mercator projection via `d3.geoMercator` and `d3.geoPath` to render GeoJSON country boundaries as SVG paths. Country fill colors are determined by a sequential blue color scale, while missing data appears gray. The code demonstrates loading remote TopoJSON and CSV files with `d3.json` and `d3.csv`, and includes an ES6 module import for a simple message.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b8ff214e24774b8fb35987f6569b93e6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
