{"version":"1.0","type":"rich","title":" activity 6_Task 1","description":"This bar chart displays the population of 30 countries in 2020, sorted along a vertical band scale. The visualization is built with React and D3 v5, using `scaleBand` for the categorical country axis and `scaleLinear` for the population axis, with SVG rectangles drawn by the `Marks` component. The data is loaded asynchronously from a CSV file using `d3.csv`, and the population values are formatted in billions using D3’s `format` function. Tooltips reveal the exact population value for each bar on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d853638f0cba45a48efbac7e878b4158?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
