This pie chart displays the proportional distribution of six product categories by value, with each slice labeled directly at its centroid. The visualization uses D3.js v7’s `d3.pie()` and `d3.arc()` generators to compute arc paths from CSV data loaded via `d3.csv()`. A category-10 ordinal color scale assigns distinct hues to each slice, while white stroke separates adjacent segments. The SVG is centered within a fixed 450×450 viewport, and text labels are positioned using the `arc.centroid()` method.
