This stacked bar chart shows how phone brand influences the distribution of ratings across five percentage categories. Built with D3 v7, the SVG visualization uses `d3.stack()` to aggregate proportions and `d3.scaleBand` for brand grouping, with `d3.scaleOrdinal` assigning colors to rating categories. Hover interactions reveal exact percentages via a custom tooltip, while the data comes from a CSV file mapping brands like Apple and Samsung to their rating breakdowns.
