This grouped bar chart compares survey responses about police politeness across six education levels, from “no education” to university. Each education level is broken into five agreement categories, ranging from “completely disagree” to “completely agree.” The chart uses d3.scaleBand for the grouped bars and d3.scaleOrdinal for color encoding, rendering in SVG within a React framework. Data comes from a CSV file, with percentages displayed on the y-axis.
