A bar chart depicts company profit growth over time from 2018 to 2030. The chart uses a static dataset of financial records with year and profit values. Built with React and D3 v5, the visualization renders scalable vector graphics (SVG) and employs `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. Bars are colored indigo, with grid lines and tick labels formatted in millions, and the chart includes a title and a legend.
