How the Distribution visualiser works
/wca/viz renders one or more cubers' complete WCA results as a kernel density estimate (KDE) curve, showing the shape of their result distribution — peak, spread, and tail. Multiple cubers can be overlaid, and the timeline can be animated by competition.
Core concept
KDE smooths a discrete sequence of results into a continuous probability-density curve with adaptive bandwidth (Silverman's rule of thumb). The x-axis is result (single); y-axis is density. A tall, narrow peak means consistent; wide means high variance. Top cubers show a sharp spike close to their personal best.
How to use
Data source
Results are fetched live from the WCA API (per cuber + event) and kept in browser memory. No server-side caching — refreshes on every page load. Speed depends on WCA API response time.
