{"version":"1.0","type":"rich","title":"Refactored Bar Chart","description":"This visualization displays a horizontal bar chart of the top 10 countries by population in 2020, using data loaded from a CSV file of UN population estimates. The example demonstrates how to structure a React-based D3 chart with clearly separated axis and mark components, with margins applied to position the left and bottom axes. It uses D3 v7’s scaleBand and scaleLinear for scales, react-fragments to render SVG groups, and a custom useData hook with d3.csv for data fetching. The chart highlights the importance of margin configuration for effective axis placement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c546c620035a4d74b91773d5c30cf2bc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
