{"version":"1.0","type":"rich","title":"Refactored Bar Chart","description":"A horizontal bar chart displays the top 10 countries by 2020 population, sourced from a UN population CSV loaded via `d3.csv`. React components render SVG axes and marks, with `d3.scaleBand` mapping countries to vertical bands and `d3.scaleLinear` mapping population values to bar widths. The chart includes custom `AxisBottom` and `AxisLeft` components with tick lines and labels, demonstrating a modular React+D3 refactoring pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eabc4fc761044f00b5318a3a45c00428?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
