Hovering over a segment reveals its exact percentage via a tooltip. The visualization uses d3.stack to generate the stacked data, d3.scaleOrdinal for color encoding, and d3.scaleBand with d3.scaleLinear for positioning. Data comes from a CSV file, and the SVG rendering includes a custom legend and axis labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bd42b536bdfd466aad5b30fbb490e243?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
