This visualization shows how salary distributions vary across four experience levels—Entry-level, Mid-level, Senior, and Executive—in a dataset of employee salaries. It uses kernel density estimation to create a smooth violin plot for each group, displaying the full range of salary values on the y-axis using a linear scale. The chart is rendered as an SVG using D3 v4, with axes and a title added directly to the SVG canvas. Data is loaded from an external CSV file and processed with d3.nest and d3.area to generate the symmetric density shapes.
