A bar chart visualizes XYZ Foods stock price from 2011 to 2016 and projected capital through 2044, with values drawn programmatically from a `FinancialPlan` class rather than static CSV data. The chart uses SVG rectangles with `d3.scaleBand` and `d3.scaleLinear` for axes, and includes animated transitions on load via `transition().ease(d3.easeLinear)`. Hovering highlights a bar in orange via mouseover handlers, expands its dimensions, and displays a dollar-value label; mouseout reverts the bar and removes the text.
