{"version":"1.0","type":"rich","title":"activity 6_Q1_2","description":"This example shows a horizontal bar chart of the top 10 countries by population from a 2010 dataset. Built with React and D3 v5, it uses `scaleBand` and `scaleLinear` to map country names and population values to SVG rectangles. Axes are rendered using D3’s `format` with a custom tick label that converts values to billions. The chart loads data via `d3.csv` and renders the rectangles with tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e1dbcaed8df6455096e695ffe2a06987?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
