This indeed works, thanks for the idea. Now the latest version of JGEX (Release 0.80-20231101 · kovzol/Java-Geometry-Expert · GitHub) uses graph-support and batik to visualize geometry proofs.

Here is Chris Brown demonstrating Geogebra Discovery at ISSAC 2023 in Tromsø. Very impressive! Chris said that he used to think that writing software to do this in a browser was impossible, but then @kovz0l just did it!
