{"version":"1.0","type":"rich","title":"Activity_7","description":"This example shows a horizontal bar chart of the top 20 countries by 2020 population, using green bars against blue tick marks. The visualization is built with React and D3 v5, employing `scaleBand` for the y-axis, `scaleLinear` for the x-axis, and SVG `rect` elements for the marks. Population values are loaded from a CSV via `d3.csv` and displayed with `d3.format` to abbreviate numbers (e.g., \"B\" for billions). The chart includes custom axis components and a tooltip using SVG `<title>`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8128614be7544660922bebb5e5f72aef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
