{"version":"1.0","type":"rich","title":"Activity6_Question1-2","description":"This example shows the top 20 countries by 2010 population as a horizontal bar chart, with country names on the y-axis and population totals formatted in billions along the x-axis. Built with React and D3 v5, it uses `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and SVG `<rect>` elements to render each bar. The data is loaded from a CSV file via `d3.csv`, and the chart includes custom axis components and a tooltip showing the formatted population value on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f43e7a7e0a2449a959e792429937f27?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
