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.
Define a network
Define some elements or servers on a network
Define group inside network definitions
Define group outside of network definitions
Define several groups on same network
Example with 2 group
Example with 3 groups
NetworkFor network or network's component, you can add or change:
GroupFor a group, you can add or change:
You can use all sprites (icons) from the Standard Library or any other library. Use the notation
You can also use the icons from OpenIconic in network or node descriptions. Use the notation
You can use same nodes on different networks (more than two networks); nwdiag use in this case 'jump line' over networks.
Peer networks are simple connections between two nodes, for which we don't use a horizontal "busbar" network
Group on first
Group on second
Group on third

With shadow (by default)
You can change the width of the networks, especially in order to have the same full width for only some or all networks. Here are some examples, with all the possibilities:
You can define other internal networks (TCP/IP, USB, SERIAL,...).
Without style (by default)
With styleYou can use style to change rendering of elements.
