{"version":"1.0","type":"rich","title":"Sophie's version: Aggregation by Country using Excel + Dropdowns!","description":"This example displays a world map with points sized by the total views for each country, aggregated from viewer location data. A dropdown menu allows users to filter the visualization by course. The map uses a geoMercator projection and d3.geoPath to render land and graticules, while d3.scaleSqrt determines circle radii. The React app loads map data from TopoJSON and viewer statistics from a CSV file, with the dropdown implemented using the react-dropdown component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b87b627f9be445db83dd1e32d8030bd5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
