This pie chart visualizes the percentage breakdown of nutritional components, such as carbohydrates, proteins, and fats, using interactive slices with hover effects that display exact values via tooltips. A legend on the right side highlights corresponding slices when hovered, dimming non-related arcs. Built with D3 v7, the chart uses the `pie` and `arc` functions to generate the layout and `scaleOrdinal` with `schemeTableau10` for colors. Transitions and opacity changes create a smooth, interactive experience for exploring the data.
