{"version":"1.0","type":"rich","title":"Refactored & Stylized Bar Chart","description":"A vertical bar chart displays the top 10 most populous countries based on UN Population data for 2020, with the population values encoded by bar length on a linear scale and countries ordered along a categorical band scale. D3’s `scaleLinear` and `scaleBand` position the marks, while `format('.2s')` converts large numbers to readable abbreviations like “B” for billions. Tooltips expose exact values on hover. The React-based implementation separates axes and marks into reusable components, applying SVG rendering with margins and external Poppins font styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c14b955b648e4fc8931ac276118a812f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
