We'd like to use an animated SVG in Fedwiki, alas all attempts to use the Graphviz plugin fail?
Flowbase page 
Lottie page
Wiki can render SVG. We read the doco SVG Image Map (using a external markup helper service)
Apparently HTML Sanitization removes the markup required to provide the Internal Fedwiki Links.
The Graph Plugin provides the sanitized links. A definite maybe...
Testing Graph Plugin works on a forked page Graph Plugin. Alas, fails on this page Lottie SVG Animations...
digraph { WelcomeVisitors -> TestingGraphPlugin -> AboutGraphPlugin "Testing Graph Plugin" -> "SVG in IMG Tag" }
.
ToDo // open a github issue on graphviz plugin wiki. Here issue
Updated
> We're sympathetic with your desire to employ SVG features within a wiki page. We've yet found a way to do so without exposing readers to malicious javascript.
