This line chart displays company financial performance from 2018 to 2030, tracking revenue, expenses, and profit in millions of dollars. It uses the D3 library’s `scaleLinear`, `axisBottom`, `axisLeft`, and `line` APIs to render three colored lines with corresponding scatter points. The chart includes interactive hover effects via a legend that fades non-hovered metrics to 0.2 opacity. Data is embedded directly in configuration as CSV and parsed with `csvParse`.
