This visualization presents salary distributions across data science job titles using four linked D3 charts: a horizontal bar chart, a box plot, a violin plot, and a multi-set bar chart. The code loads salary data from a CSV file with job titles and salaries, sorts it, and renders the charts as SVG elements. It uses d3.scaleBand and d3.scaleLinear for the bar chart, alongside additional D3 v4 and v7 APIs for the statistical plots, all embedded in a React-based HTML page with custom CSS styling.
