{"version":"1.0","type":"rich","title":"Refactor Bar Chart","description":"A horizontal bar chart displays population estimates for ten countries from UN population data for 2020. The chart uses React with hooks to fetch and parse CSV data via D3’s `csv` utility, then renders SVG bars and tick labels using D3’s `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. The React component conditionally shows a loading state before rendering the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e118a6087640496ba35c87daa0ef667e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
