This visualization compares three coffee quality metrics—acidity, sweetness, and aroma—across countries of origin using a multi-series line chart. The code loads a CSV dataset, converts numeric columns, and renders three colored lines with data point markers using D3 scales and axis generators. It employs `d3.scalePoint` for the categorical x-axis of origins, `d3.scaleLinear` for the 0–10 score range, and `d3.line` to draw each metric series. Gridlines, rotated axis labels, and a legend clarify the chart, which renders as SVG.
