This bar chart displays the average attendance percentage for each university module, using data from a CSV file. The visualization is built with D3.js v4 and renders as an SVG, with bars animating into place via a transition. Each module is labeled on the x-axis, while the y-axis shows percentages. Hovering over a bar triggers a mouseover event that highlights it in orange, enlarges it, and displays its exact value as a text label.
