Four small multiples display scatterplots of alpine ski split times across training days and course types. Each panel corresponds to a different intermediate timing point, with points jittered along the course axis. A dropdown menu filters all panels by ski academy. The visualization uses D3 v7 with SVG rendering, custom `scatter()` and `menu()` reusable chart functions, and `d3.rollups` to aggregate means. Data comes from a CSV file loaded via `d3.csv`.
