A stacked bar chart visualizes the distribution of ice cream flavor ratings across five percentage categories, with each flavor represented as a horizontal bar segmented by rating tier. The chart uses D3.js v7 APIs including `d3.stack`, `d3.scaleLinear`, `d3.scaleBand`, and `d3.axisBottom`/`d3.axisLeft`. Data comes from a local CSV file, rendered as SVG with interactive tooltips on hover showing the exact percentage per segment.
