Reflect physical layout in device graphs

**Describe the feature you'd like**

Device paradigm properties already has connectivity, as well as a topology graph, and can be visualized in one or two lines - adding physical locations to a backend would make visualizations trivial.

**How would this feature be used? Please describe.**

Used for simple device visualization, i.e. through networkx.draw(graph, locations...)

**Describe alternatives you've considered**

There currently are none programmatically - generating a visualization from the current graph may or may not match the common physical 2d projection.

Unclear if these would have to be hardcoded, but seems likely.
