A scatterplot shows employee salaries plotted against age, with points colored by job role across six categories. The chart renders as an SVG using D3 v7, with a reusable `scatterPlot` module employing `scaleLinear`, `axisLeft`, and `axisBottom` for axes. A D3 data join renders circles, while a legend and dark-themed styling with Share Tech font present the salary distribution and role comparisons.
