This scatter plot visualizes the relationship between years of service and salary for university professors. Each circle represents an individual, with its position determined by the `d3.scaleLinear` scales mapping the x-axis (years of service) and y-axis (salary in USD). The chart uses `d3.axisBottom` and `d3.axisLeft` for labeled axes, and a 1.2-second `transition` animation grows the circles from radius zero to their final size. The data is loaded from a CSV file and filtered to include only professors with more than two years of service.
