This example presents a custom-designed donut chart depicting dietary composition, with a large title label and clearly distinguished slices for food categories. The chart renders categorical data from a CSV file using an SVG canvas. The visualization uses D3 v5 to generate pie arcs with `d3.pie` and `d3.arc`, applies an ordinal color scale from `d3.scaleOrdinal` with `d3.schemeCategory10`, and adds labels with values and percentages via `tspan` elements. Axis customization is minimal, focusing instead on the chart’s illustrative styling and annotation.
