{"version":"1.0","type":"rich","title":"Question 2","description":"A horizontal bar chart displays population change for ten countries from 1950 to 2020, with each row representing a year and bar length scaled to population. The chart uses D3 v7’s `scaleBand` for the year axis, `scaleLinear` for population, and `scaleOrdinal` with `schemeCategory10` for country colors. Interactive tooltips appear on mouseover, showing the exact year and population value. Data comes from a local CSV file loaded and parsed by D3.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/081800cc9e8e482aa7ba5e3d3fe64ad7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
