A custom graph of nodes can be selectively generated based on a selected node in a graph representative of a network-connected computing infrastructure. The custom graph can, for example, be generated using software executing on a server device. The server device can receive an indication of the selected node from a client device. A plugin can then be invoked by providing the selected node to the plugin. Responsive to providing the selected node to the plugin, the plugin can provide output including child nodes generated by the plugin. The child nodes generated by the invocation of the plugin can be iteratively processed to generate the custom graph, such as by providing those child nodes to the plugin for subsequent invocation, as applicable. After the custom graph is generated, it can be transmitted to the client device from which the indication of the selected node was received. The custom graph may be displayed at the client device.
