Walkthrough

A new "Community Solutions Analysis" feature was introduced to the course admin area. This includes a new route, controller, model, component, and templates for displaying per-stage code solution statistics by language. The implementation covers data fetching, computed statistics, color-coded presentation, and navigation enhancements within the course admin interface.

Poem

In burrows deep, the data flows,
New stats and charts the admin shows.
With colored cards and clever code,
Each language’s secrets are now bestowed.
Hop along, explore, don’t lag—
For every stage, a brand new flag!
