Connections between devices Devices
A physical topology diagram or network diagram, would show the actual physical devices on a network and how they connect to each other. This is often useful in determining how to expand a network or upgrade one. There are several software packages that do an excellent job of producing the diagram, so it is unlikely this would be done manually. Plus, networks are dynamic enough that you would want some type of automated way of producing the diagram.

The Lifshitz point in a material's phase diagram is a critical point where the topology of the Fermi surface changes, leading to unique electronic properties. It marks a transition between different phases and can influence the material's behavior, such as its magnetic or superconducting properties.
An electric switch diagram typically shows key components such as the switch itself, power source, and connected electrical devices. It also illustrates the connections between these components, indicating how the switch controls the flow of electricity to the devices.

It is a hybrid between Use Case and Sequence Diagram
A Venn diagram or a set diagram is a diagram that shows all possible logical relations between a finite collection of sets.
A Venn diagram is a diagram that shows relationships between 2 things or concepts using circles if there are similarities between both then you overlap the circles.
