This example visualizes the relationship between years of experience and salary compensation using a bar chart built with D3 v7. It shows how salary values scale across different experience levels, with the y-axis formatted in dollars and the x-axis displaying experience values. The visualization loads data from a CSV file via `d3.csv`, then uses `d3.scaleBand` and `d3.scaleLinear` to map the data to screen coordinates. Bars are rendered as SVG `<rect>` elements, while axes are generated using `d3.axisBottom` and `d3.axisLeft` for clear quantitative comparison.
