{"version":"1.0","type":"rich","title":"Activity6Question2","description":"This example displays population changes for several countries from 1950 to 2020 using a horizontal bar chart. Each country is assigned a distinct color, and bars extend horizontally to represent population values for each year, with years arranged vertically. The visualization loads D3 v7 via UNPKG, uses `d3.scaleOrdinal` for color assignment, `d3.scaleBand` and `d3.scaleLinear` for axes, and `d3.axisBottom` and `d3.axisLeft` for tick marks. Mouse interactions update a tooltip showing the exact year and population. The underlying data comes from a CSV file containing country names, codes, and yearly population figures.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/57a04c604adb4d2bbc8a32b9962040c5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
