{"version":"1.0","type":"rich","title":"E23 - Refactoring a Bar Chart","description":"This bar chart shows the number of trips per region, rendered as horizontal bars using SVG within a React component. The code imports `scaleBand` and `scaleLinear` from d3 to map data to pixel coordinates, while React’s `useState` and `useEffect` handle asynchronous CSV loading via d3’s `csv` method. The `AxisBottom`, `AxisLeft`, and `Marks` components are separated for reuse, producing a clean, refactored visualization with a left margin aligned to the region labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ae261ff51294476aa1971f913765f61?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
