{"version":"1.0","type":"rich","title":"Untitled","description":"This example visualizes global population data from a 2019 UN dataset, displaying each country as a rectangle in a bar-chart-like SVG layout. The chart maps country names to vertical positions using a D3 scaleBand, though the rectangles are left with placeholder width and height values. The code loads the CSV data with D3’s `csv` utility and manages asynchronous data fetching with React hooks (`useState`, `useEffect`). React renders the SVG elements directly, while D3’s scaling functions handle the band positioning for each row.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/12a0eddb65ed4c5d9707d16f447cde98?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
