What is language heat?

A daily share of the spotlight.

Each day's heat is the language's appearances divided by all labeled appearances on the daily Trending list. Repeated appearances on different days reflect continued attention.

Unlabeled entries are excluded. This measures attention on GitHub Trending, rather than overall language adoption.
