Issue

Resolves #3464

What's Changed

Added a clear, simple example in the Compression section of the user guide showing how to create an array without compression by setting compressors=None.

Why This Matters

  • Addresses common user confusion about default compression behavior
  • Provides an easy-to-copy example for disabling compression entirely
  • Complements existing examples that show compression with various codecs

Testing

  • ✅ All pre-commit hooks pass (ruff, mypy, codespell, numpydoc)
  • ✅ Full test suite passes (5328 tests)
  • ✅ Documentation builds cleanly
  • ✅ Example code verified in built HTML

Changes

  • Added uncompressed array example in docs/user-guide/arrays.md
  • Created changelog entry changes/3464.doc.md

Add a clear, simple example in the Compression section of the user guide
showing how to create an array without compression by setting compressors=None.

This addresses user confusion about the default compression behavior and
