{"version":"1.0","type":"rich","title":"Activity 7","description":"This example shows a horizontal bar chart of population data for 20 countries in 2020, with bars arranged by country and length proportional to population. The visualization uses React with D3 v5's `scaleBand` and `scaleLinear` to map data to SVG rectangles, with axes rendered via custom `AxisBottom` and `AxisLeft` components that use D3’s `format` function to abbreviate large numbers. The data is loaded asynchronously from a CSV file using D3’s `csv` method, and interactive tooltips display the formatted population value on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/03080652e54b491a98d6d8b57b17d05d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
