I think you'll probably run into performance problems with SVG before you get too far. I can't imagine SVG will perform fluidly with complex circuit boards.

SVG elements are DOM elements after all, and too many DOM elements will cause browser performance issues. I know this the hard way, after adding a few hundred SVG <path> elements with a few hundred <div> elements in a React-based interactive web application, I ended up needing to move to a canvas solution instead, which works amazingly well.

I really hope you have all that figured out, because I don't think it's going to work well using SVG to render complex circuit boards. But maybe your product is only working with very simple circuit boards?
