A grouped bar chart visualizes car accidents in Greece for 2022 by passenger category, comparing total, lethal, and non-lethal counts across seven configurations such as drivers-only and pedestrian-involved crashes. The chart uses D3.js v6 with an SVG rendering, employing `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis. Bars are color-coded with cyan for totals, purple for non-lethal, and crimson for lethal accidents, as defined in the stylesheet. Data comes from a CSV file based on Greek statistics authority records.
