Embodiments disclosed herein generally relate to techniques for providing a visualization of connectivity between components in a computer network. One embodiment provides a method which includes receiving a configuration of a network comprising a plurality of components within a physical layer and a virtual layer. The method also includes generating a resource diagram identifying connections that are accessible among the components of the physical layer and components of the virtual layer. The method further includes, upon receiving a selection of one of the components, determining a subset of the plurality of components that are connected to the selected component, and altering the resource diagram to provide a visualization, within the resource diagram, of the connections between the selected component and the determined subset of the plurality of components.
