The chart uses `d3.stack()` to compute the stacked series, `d3.scaleBand` for the categorical x-axis, and `d3.scaleLinear` for the y-axis, rendering with SVG rectangles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a65fe983ed824dcc861af40cf2c720a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
