A scatter plot displays module marks for individual courses, with each circle’s vertical position representing a module code and horizontal position showing its mark. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear` for the x-axis and `scalePoint` for the y-axis. Data loads from a local CSV file via d3.csv, and axes are generated with `axisLeft` and `axisBottom`. Grid lines extend across the plot through tick sizes, while a labeled axis and title provide context.
