# Graphs Eng

**Graphs Eng** tool is an OntoGuiWeb module that visualizes graphs representing parts/part types (i.e. bill of material - BoM), processes (i.e. bill of process - BoP), and production systems (i.e. system layout in terms of workstations and buffers). 

This tool is based on the GraphViz library and supports the export of graphs in SVG, PNG, and DOT format.
