{"version":"1.0","type":"rich","title":"Refactored Bar Chart","description":"This example presents a bar chart of population data for the top ten countries in 2020, sourced from a CSV file via a custom React hook that uses D3’s `csv` utility. The visualization is rendered as SVG, with React components for the axes (`AxisBottom`, `AxisLeft`) and bars (`Marks`), using D3 scales (`scaleBand`, `scaleLinear`) to map country names and population values to pixel coordinates. The chart loads asynchronously and displays a placeholder while fetching data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9059d28733f64c95a04de6c6ea7720d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
