This visualization presents a stylized horizontal bar chart that ranks academic modules by student enrollment numbers. A dropdown menu allows users to filter the displayed data by department codes (CSIS, CAM, GAV), though the implementation for this filtering is not shown in the core rendering logic. Built with React components and D3 v5, the chart uses `d3.scaleBand` for the y-axis categories and `d3.scaleLinear` for the quantitative x-axis, rendering orange SVG rectangles within an 800x5000 pixel canvas. The data originates from a CSV file containing module codes and student counts.
