This scatter plot visualizes the average marks achieved across various modules, with each circle representing a course positioned by its mark on the x-axis and module name on the y-axis. The chart uses D3 v5's `scaleLinear` and `scalePoint` for axes, while `axisLeft` and `axisBottom` generate the tick marks. Data is loaded from a CSV file and rendered as SVG circles with steelblue fill. The visualization includes axis labels and a title, with styling applied via CSS.
