Traceroute Visualizer

Paste the raw output from Linux/macOS `traceroute` or Windows `tracert` and get an interactive visualization: per-hop RTT bar charts colored by latency quality (excellent/good/fair/slow/poor), private IP range annotations (RFC1918, link-local), timeout indicators, and a full per-probe timing table.

Supports both traceroute and tracert formats with automatic detection. Summarizes total hops, non-responsive hops, and maximum RTT. Useful for diagnosing network path issues, identifying where latency is introduced, and visualizing internet routing for presentations.
