This area chart displays the aggregated chocolate ratings from a CSV file, showing the proportion of ratings that fall into the "More than 6" category for each chocolate type. The chart uses D3.js v7 to load the data via `d3.csv`, render an SVG path with `d3.area`, and add axes using `d3.axisBottom` and `d3.axisLeft`. The area is filled in steelblue, and categorical labels on the x-axis are rotated for readability.
