This line chart shows the average aroma score for each coffee origin, with origins sorted alphabetically along the x-axis. The chart uses a point scale for origins and a linear scale for scores, with the line connecting points to reveal trends across regions. d3.csv loads the coffee dataset, and d3.rollups computes mean aroma values per origin. The SVG rendering includes rotated tick labels for readability and interactive tooltips on each data point via SVG title elements.
