This bar chart visualizes average salaries for data science job titles, loaded from a CSV file via `d3.text`. The visualization uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis to render the SVG bars. Interactive tooltips appear on mouseover, changing the bar’s fill color to orange and displaying the job title and salary. Axis labels, a chart title, and rotated x-axis text are added using D3’s axis components.
