This visualization presents company financial performance over time, showing revenue, expenses, and profit for each year from 2018 to 2030. It uses grouped bar charts where lighter bars represent expenses and darker bars overlay to show revenue, with profit values labeled above each bar. The implementation combines React's state management with D3.v7 for rendering, using `scaleBand` for the x-axis years, `scaleLinear` for the y-axis amounts, `axisBottom` and `axisLeft` for axes, and a `ResizeObserver` for responsive sizing. Clicking a bar highlights that year's data.
