## Overview

This repository is a reference library, not a software runtime: utility-network practitioners use its electric diagrams and modeling patterns as configuration examples. The tree organizes examples across distribution, generation, subtransmission, and transmission, with separate general modeling references. The README documents the library’s purpose and PDF/image formats; no source excerpts are available, so the graph does not infer links between individual examples or domain categories.

Main entry points: [`README.md`](https://github.com/esri/utility-network-modeling/blob/dev/README.md) (Configuration library)
