C4 is a language for describing systems. I use structurizr to catalog everything and to better understand the relationships and problems. It can then create multiple views. For instance focus on one component and filter which relationships to show. I end up with 8 or more views, a few of which are useful to highlight a problem or problematic dependency. It can export plantUML as well as SVG. plantUML is more open and more widely applicable. C4 is a process of cataloging.
