{"version":"1.0","type":"rich","title":"Bar Chart","description":"This bar chart displays the top 10 countries by estimated 2020 population, using horizontal bars ranked from largest to smallest. The visualization loads CSV data from a GitHub gist, which is parsed with `d3.csv` and structured in React state via a custom `useData` hook. The x-axis uses a `d3.scaleLinear` range mapped to population values, while the y-axis uses a `d3.scaleBand` for country categories. SVG elements are generated by React components for axes and marks, with `d3.format` applied to abbreviate tick labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b82855c85b64262a277dd011e2db61d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
