This bubble chart displays the sales information for a group of employees, plotting each person's total sales against their net profit, with the size of each bubble representing the units sold. The visualization uses D3 v7 to load data from a CSV file and render the chart as an SVG. Interactive tooltips appear on mouseover, and it includes axes labels, a bubble size legend, and a color scale using `d3.interpolateTurbo` to differentiate employees.
