{"version":"1.0","type":"rich","title":"Lets make a map","description":"An interactive choropleth of South Korea lets users click any district to see its vote distribution rendered as a pie chart. The map is drawn with `d3.geoPath` and a Mercator projection, while district names come from a CSV mapped by `SIG_CD`. Clicking a city triggers a pie chart built with `d3.pie` and `d3.arc`, populating a second SVG. The visualization relies on TopoJSON for district boundaries, D3’s `select`, `csv`, and `json` loaders, and encodes vote counts from a separate CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2c65d9a310f340faace9518c2f20d4af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
