A
network diagram is a visual representation of a computer or telecommunications network. It illustrates the
arrangement and interconnections of network components, including servers, routers, switches, hubs, and devices. Network diagrams are invaluable tools for network engineers and administrators to
understand, set up, and troubleshoot networks. They are also essential for
visualizing the structure and flow of data in a network, ensuring optimal performance and security.
nwdiag, developed by
Takeshi Komiya, provides a streamlined platform to swiftly sketch
network diagrams. We extend our gratitude to Takeshi for this
innovative tool!
Given its intuitive syntax,
nwdiag has been seamlessly integrated into
PlantUML. The examples showcased here are inspired by the ones documented by
Takeshi.
