Graph authors use Polygrad's public C headers and generated extension bindings.
Redistributed Polygrad headers retain their MIT license in POLYGRAD_LICENSE.
Polygrad itself is an optional runtime dependency, not linked into the graph authors.

The UMAP and TriMap implementations have algorithmic differences documented in
README.md; umap-js, umap-learn, scikit-learn and trimap are test references,
not bundled runtime dependencies.

The base backend's exp/log/log2/pow routines and tables derive from musl,
as distributed by Emscripten commit dc80f645ee70178c11666de0c3860d9e064d50e4.
