A scatterplot depicts the relationship between average digs and average hitting percentage for NCAA Big Ten volleyball teams, with each point colored by school and animated over the 2012–2019 seasons. The visualization uses D3.js (d3.v7) to parse a CSV, compute team-year averages via `d3.rollups` and `d3.mean`, and render SVG circles filled with team logos from external PNG files. Team colors and fallback pattern images are defined in JavaScript.
