This area chart displays the average Aroma Score for coffee beans grouped by origin, with origins sorted alphabetically along the x-axis and mean scores plotted on the y-axis. The visualization uses D3 v7 to load a CSV file, aggregate the data with `d3.rollups` and `d3.mean`, and render smooth paths via `d3.area` and `d3.line` with a monotone curve. SVG axes are generated using `d3.axisBottom` and `d3.axisLeft`, with rotated tick labels for readability.
