This fork of a bar chart visualizes the relationship between years of experience and salary. It renders steel-blue SVG rectangles using D3.js v7, with an x-axis for experience and a y-axis formatted to display salary in dollars. The code loads CSV data from a GitHub gist and uses `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft` to construct the chart. A title and axis labels are added as text elements, and the SVG is sized at 800 by 600 pixels.
