{"version":"1.0","type":"rich","title":"Refactored Bar Chart","description":"A refactored bar chart visualizes the populations of the ten most populous countries in 2020. The chart uses React state via a custom hook to manage data loading, while D3.js utilities handle scaling and drawing. SVG rendering with `scaleBand` and `scaleLinear` positions horizontal bars, with axes and marks split into separate components. Population data comes from a UN CSV file fetched using D3's `csv` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c7a3c9946d3b494dbae2573494db74d0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
