This chart displays a synthetic household budget allocation as an animated, labeled pie chart built with D3 v7. It breaks down spending across eight categories like Housing and Transportation, showing each slice’s percentage via labels connected by leader lines. The visualization uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with `d3.schemeTableau10`, rendered as SVG. A legend lists categories with color swatches, and hovering over slices reveals a tooltip with exact values and percentages.
