+# LAN Graph Explorer
+
+A local LAN discovery service that pings every host on your primary subnet, optionally uses SSH key-based auth to query remote neighbors, and presents a Visio-style map via D3.
+
+## Features
+- Detects your default IPv4 network and gateway automatically.
+- Pings each active host and performs reverse DNS lookup.
+- Attempts passwordless SSH (honoring `SSH_USER`/`SSH_KEY_PATH`) to collect `ip neigh` data so we can draw edges between hosts.
+- Serves a FastAPI backend and a D3-powered front-end that renders nodes/edges interactively.
+
+## Getting started
+1. Install dependencies (ideally inside a virtualenv):
+   ```bash
+   pip install --upgrade pip
+   pip install fastapi uvicorn[standard] typer
+   ```
+2. Run a scan from the command line:
+   ```bash
+   lan-graph scan --concurrency 64 --ssh-timeout 5
+   ```
+3. Start the UI server:
+   ```bash
+   lan-graph serve --host 0.0.0.0 --port 8000
+   ```
+   Open `http://localhost:8000` in a browser to see the topology.
+
+## SSH key authentication
+Set environment variables so the scanner uses your preferred SSH identity:
+```bash
+export SSH_USER=team
+export SSH_KEY_PATH=~/.ssh/id_rsa
+```
+The tool runs `ssh -o BatchMode=yes` and will skip hosts where it cannot connect quickly.
+
+## Testing
+```bash
+pip install pytest
+pytest
+```
+
+## Notes
+- The graph draws gateways, the scanning host, and any discovered neighbor relationships for hosts that allow `ssh`.
+- It's designed to run on Linux machines with `ip`, `ping`, and `ssh` in place.
