This visualization displays the distribution of horsepower percentages across different car models using a stacked horizontal bar chart. Each bar represents a car model, with colored segments corresponding to horsepower ranges. The chart uses D3.js v7’s `d3.stack`, `d3.scaleOrdinal`, `d3.scaleLinear`, and `d3.scaleBand` to compute and render stacked segments as SVG rectangles. Interactive tooltips, styled via CSS, reveal the exact percentage for each range on hover. Data originates from the included `data.csv`, read as a static D3 dataset.
