This visualization displays the distribution of fuel efficiency (mpg) for the top five automobile makes—Hyundai, Honda, Kia, Scion, and MINI—across multiple model years. It combines box plots showing quartiles, median, and whisker ranges with individual green data points jittered along the x-axis to reveal underlying data density. Built with D3 v4, the chart uses `d3.nest()` and `d3.quantile()` to compute summary statistics from a CSV file, then renders SVG rectangles, lines, and circles with hover tooltips for each point.
