This interactive dashboard visualizes sleep disorder prevalence across low, medium, and high stress levels, using 100% stacked bars with animated transitions. Users filter by gender and toggle between all categories or disorders only, with hover tooltips and clickable legend items that isolate healthy versus disordered sleep groups. Built with React and D3 v7 (d3.scaleBand, d3.stack), the SVG chart renders from a CSV dataset and updates bins and counts dynamically. The animation and ordinal color scale highlight how higher stress correlates with increased Insomnia and Sleep Apnea rates.
