{"version":"1.0","type":"rich","title":"side by side barchart","description":"This side-by-side bar chart compares fertility rate, birth rate, and life expectancy across continents using a grouped bar layout. Each continent displays three colored bars—steelblue for fertility, orange for birth rate, and green for life expectancy—all sharing a common y-axis of mean values. Built with D3 v7 in a React environment, the visualization renders SVG rectangles positioned via `d3.scaleBand` and `d3.scaleLinear`, with data fetched from a CSV file hosted on GitHub. A legend and axis labels clarify the encoded metrics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e86c6d56aa84423b8b7593710840186a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
