This bar chart tracks company profit from 2018 to 2030, with each year’s profit value labeled above its corresponding bar. Built with React and D3 v5, the visualization uses `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the y-axis, and SVG rendering. Synthetic financial data provides the year and profit values, while CSS drop-shadow filters and hover effects add visual depth.
