{"version":"1.0","type":"rich","title":"Act 6 task1","description":"A horizontal bar chart displays 2020 population estimates for 30 countries, sorted by country name, with green bars and blue tick marks. The visualization uses React with D3 v5 scales (`scaleBand`, `scaleLinear`) to map country names to y-axis positions and population values to bar widths, rendering SVG rectangles via a custom `Marks` component. Data loads asynchronously from a GitHub-hosted CSV file using `d3.csv`, and axis labels are formatted with D3's `format` function to abbreviate large numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/684f0162bab143898e6c784056b18133?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
