{"version":"1.0","type":"rich","title":"Refactored Bar Chart","description":"This example displays a horizontal bar chart of the top ten countries by population in 2021, using a linear scale for bar lengths and a band scale for row positions. It loads data from a CSV file via D3’s `csv` utility, then renders SVG rectangles and custom axis components built with React. The `AxisBottom` and `AxisLeft` components create tick marks and labels, while the `Marks` component maps each data row to a `rect` element. React’s state management, via `useState` and `useEffect`, handles asynchronous data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ead89240667e4b418df02656f2b19616?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
