This bar chart displays the average aroma score for coffees grouped by their country of origin, based on data from a CSV file. The visualization uses D3 v7 to load the dataset, compute the means with `d3.rollups` and `d3.mean`, and render an SVG with `scaleBand` and `scaleLinear`. Bars are drawn with the `join` method and axes are labeled. The chart helps compare which origins produce higher-rated aromas visually.
