This bar chart displays average salaries by job title for U.S. states, with each bar’s height representing the population value. The visualization uses D3.js v6 to fetch CSV data from a Plotly-hosted dataset, parse it client-side, and render an SVG with axes and tooltips. Hovering over a bar changes its fill to orange and reveals a tooltip with the job title and salary. The chart applies a band scale for categorical x-axis labels, a linear scale for the y-axis, and rotates tick labels for readability.
