The chart is built with D3 v5 using nested data from a CSV file, rendered as SVG. It employs `d3.nest()` for grouping, `d3.scalePoint` for the y-axis, `d3.scaleLinear` for years, and `d3.scaleOrdinal` with the `schemeAccent` color palette, alongside `d3.axisLeft` and `d3.axisBottom` for axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5a37fd4b792b445a8a377fbdf410bb24?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
