The visualization compares one-year versus ten-year costs for two job roles, shown as a pair of side-by-side pie charts. It uses D3 v5’s `d3.pie` and `d3.arc` to generate the slices, with `d3.scaleOrdinal` assigning categorical colors. Data is loaded from two separate CSV files via `d3.csv`, and both charts are rendered as SVG inside a shared `<svg>` container. The title “one year cost vs ten years” and dollar-value labels make the quantitative comparison explicit.
