This bar chart displays the number of Hogwarts students in each of the four houses, using the Chart.js library with canvas rendering. It shows Gryffindor, Slytherin, Ravenclaw, and Hufflepuff in their canonical colors, with counts derived from a CSV file. The code fetches the data via the fetch API, processes it by counting house occurrences, and draws the chart with explicit axis titles and a hidden legend.
