This stacked bar chart shows the percentage distribution of five rating levels across seven restaurants, using horizontally oriented bars where each segment represents a rating category. The visualization employs d3.stack() to compute stacked series from CSV data, d3.scaleBand() for the categorical y-axis, and d3.scaleLinear() for the percentage x-axis. Color encoding via d3.scaleOrdinal distinguishes rating bins, while mouseover events trigger tooltip displays showing exact percentage values. The SVG rendering includes axis labels, a title, and grid lines, with data sourced from dataQ2.csv.
