{"version":"1.0","type":"rich","title":"Let's make a yunnan map with D3.js!","description":"An interactive D3.js map of Yunnan Province visualizes population data across its administrative regions as semi-transparent circles sized by a square-root scale. Built with d3.geoMercator for projection and d3.geoPath for rendering GeoJSON boundaries, the map supports zooming and panning via the d3.zoom API. The choropleth uses a two-tone fill to distinguish regions with data from those without, while a legend explains the circle sizing. Population statistics are loaded from a CSV file and joined to geographic features using TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c6aa17110f3346a2b43b648d9a5880d9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
