{"version":"1.0","type":"rich","title":"Activity 1_task 1","description":"This example displays a horizontal bar chart of population figures for 30 countries in 2020, using D3 scales for positioning and React for rendering. It loads comma-separated data from a GitHub-hosted CSV file, parsing the `2020` column and multiplying by 1000 to represent population. SVG rectangles are generated from the `Marks` component, with axes drawn using `scaleBand` and `scaleLinear` and formatted with D3's `format` function, converting Giga to Billions for labeled ticks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1222700a41ca4b19ac069c8b4cd0f204?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
