This chart shows the gender distribution of students across numerous game design and media modules, with stacked bars representing males and females for each course. A radio button toggle switches between absolute counts and percentage-based views, animating the transitions smoothly. The visualization uses D3.js version 3.5.6, leveraging the `d3.layout.stack()` API with dynamic offset switching ("zero" vs. "expand"). The SVG rendering, driven by a CSV data file, sorts modules alphabetically and employs category colors with a custom legend. Hovering highlights individual bars through CSS opacity changes.
