This pie chart displays the sales distribution for ten product types, ranging from Plushies with 5000 units to Watches with only 30 units. The chart is rendered as an SVG using the D3.js v4 library, with each slice colored via a custom ordinal palette. The code defines a fixed dataset inline, uses `d3.pie()` to compute the arcs, and `d3.arc()` to draw them. A clickable legend is positioned to the right, although the click handler does not implement filtering logic.
