## Summary by CodeRabbit
- **New Features**
- Enhanced graph analytics now offer detailed metrics—including shortest
path lengths, diameter, and clustering coefficients—to provide deeper
insights.
- Added new functions for creating connected test graphs and validating
metrics against predefined ground truth values.
- Introduced a new JSON file containing metrics for connected and
disconnected graph structures.
- **Improvements**
- Updated how graphs are projected to consistently use undirected
representations, ensuring more accurate and reliable metric
calculations.
- Streamlined metric consistency checks across different graph
processing methods for robust, reliable results.
- Simplified testing logic by consolidating metric assertions into a
single function call.
- **Chores**
- Removed unnecessary secret variables from the workflow configuration,
potentially affecting access to certain resources.
- Updated secret management to include the new `OPENAI_API_KEY`.
