{"version":"1.0","type":"rich","title":"Activity 6_Task 1","description":"This example visualizes the top 30 most populous countries in 2020 using a horizontal bar chart, with each bar’s length encoding population size. The chart is built with React and D3 v7, using `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis categories. Population data is fetched from a CSV hosted in a GitHub gist, with a hardcoded fallback dataset in case the request fails. The visualization renders as SVG, with custom React components for the axes and marks, and includes styled hover effects and axis labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3d517c0e4f4a4f7cbbee33a1e2b43025?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
