This example displays a bar chart of average salaries by job title, with each bar colored steel blue and highlighted orange on hover. It fetches CSV data from a remote gist using `d3.text`, parses it into job title and salary pairs, and renders the chart as SVG via D3 v6. The visualization uses `d3.scaleBand` and `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and includes a tooltip div that appears on mouseover showing the job title and formatted salary.
