The CGAL Project
@cgal • CGAL is a software project that provides easy access to efficient and reliable geometric algorithms in the form of a C++ library.. Use this route to separate flagship concentration from portfolio breadth before you treat a publisher as broadly strong.

Why this rank
This organization stands out because one flagship repo drives 92% of its visible star count.

Organization pages work best when you separate portfolio breadth from flagship concentration. In The CGAL Project's case, the visible top three repositories account for about 99% of total stars in this snapshot, which helps explain whether the organization is known for one breakout project or for a broader repeatable portfolio.
The dominant language mix here is C++ (7), Python (5), Shell (5). That makes this page useful not just for popularity checks, but also for seeing what technical shape an organization's public ecosystem actually has.

How to read this organization snapshot
Total stars are useful as a discovery signal, but they do not tell you whether a team maintains every repository equally. Pair this page with release cadence, maintainer activity, and the flagship concentration shown above before making adoption decisions.
