{"version":"1.0","type":"rich","title":"Activity6_task-1","description":"This example displays a horizontal bar chart of the top 30 countries by 2020 population, using SVG rectangles scaled by a linear population axis and a categorical country axis. The visualization loads data from a CSV file and formats population values in billions with D3's `scaleLinear`, `scaleBand`, and `format` utilities. React components render the axes and marks, with tooltips provided by SVG titles and blue axis ticks styled via CSS. The chart highlights D3 v5 integration within a React framework, demonstrating basic data loading and declarative chart construction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/63906fd749dc42ae86ff5417a7f89b94?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
