I’ve been using SVGs in my robot mapping software and it’s amazing how powerful they are. I design them using css custom properties (variables) so that I can style icon colours, borders, etc. at runtime.
Proprietary so I unfortunately can’t show, but I develop a Web-GIS for lidar mapping of warehouse environments, annotating the space for driving rules (urban planning / Sim City), and real-time site monitoring/issue fixing (like an RTS strategy game) for >10k robots worldwide.
