This bar chart displays the average attendance percentage for each module, with bars colored steelblue and one highlighted in orange. It uses d3.v4 to bind data from attend_data.csv to SVG rect elements within a 600×500 viewport. The x-axis maps module codes while the y-axis encodes attendance values, with margins set via a margin object. The chart reads from a preprocessed CSV and renders statically without transitions or interactive features.
