-# Note for Hugging Face Spaces:
-# Grape requires Rust to be installed for compilation
-# If deployment fails, consider using NetworkX as fallback:
-# networkx==3.1
-# 
-# For local development with Grape:
-# 1. Install Rust: https://rustup.rs/
-# 2. Run: pip install grape-graph
-#
-# Alternative: Use pre-compiled wheels if available:
-# pip install --only-binary=grape-graph grape-graph
+# Note: NetworKit provides high-performance graph algorithms
+# Much faster than NetworkX while being compatible with HF Spaces
+# No Rust compilation required - uses optimized C++ backend
