{"version":"1.0","type":"rich","title":"activity 6_Task 1 ","description":"This visualization displays the populations of 20 countries in 2010 as a horizontal bar chart, using React and D3 v5 to render the SVG elements. It loads data from a CSV file via a custom `useData` hook with `d3.csv`, then uses `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. The bars are drawn as SVG `<rect>` elements with a native `<title>` tooltip showing formatted population values, and tick marks are generated using `xScale.ticks()` with custom formatting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad4a9beade0c45f591ee8f40dfede526?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
