{"version":"1.0","type":"rich","title":"Refactoring a Bar Chart","description":"This bar chart displays the population of the top 10 countries from the UN Population 2019 dataset. React components render SVG rectangles for each bar, with the x-axis scaled by `d3.scaleLinear` and the y-axis using categories from `d3.scaleBand`. The code defines reusable `AxisBottom`, `AxisLeft`, and `Marks` components, and loads data asynchronously with `d3.csv` inside a custom `useData` hook, while D3 utilities like `max` and `scaleBand` handle the scaling logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b3cacd612b4b460a90a72f6d30cb01f3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
