This visualization presents a stacked bar chart displaying patient details, with each bar representing a patient and segments showing the percentage contribution of different attributes such as age, weight, and height. The chart uses a horizontal layout, with bars stacked by category and color-coded via a scaleOrdinal palette. Hovering over a segment reveals a tooltip with the exact percentage value for that category. The implementation uses d3.v7's stack, scaleLinear, and scaleBand APIs, rendering as SVG with data loaded from Patientdata.csv, and includes interactivity through mouseover events.
