I wanted a diagram to visually represent the stack of tools, in my case centered around Kubernetes which actually make up the Platform which folks build on top of in a company. Couldn't find an easy way to do that, so built a tool for it - you give it a simple YAML config file with a list of tools organised into groups, it downloads SVG logos and builds a graph diagram for you. Hope it helps someone!
