For larger networks, Python-based NetBox from Digital Ocean can generate some diagrams from network asset database. https://github.com/netbox-community/netbox https://github.com/netbox-community/netbox > NetBox functions as the source of truth for your network infrastructure. Its job is to define and validate the intended state of all network components and resources. NetBox does not interact with network nodes directly.. This separation of duties enables the construction of a robust yet flexible automation system. https://github.com/netbox-community/devicetype-library https://github.com/netbox-community/devicetype-library > Each file represents a discrete physical device type (e.g. make and model). These definitions can be loaded into NetBox instead of creating new device type definitions manually. https://github.com/Abulhallaj/netbox-deviceimage https://github.com/Abulhallaj/netbox-deviceimage > Device images in PNG format and arranged by manufacturer. Each file represents front and rear of a physical device type (e.g. make and model). These images [based on vendor visio stencils] can be loaded into NetBox to obviate the need to create device images.
