If a vector graphic is saved as a PDF (rather than an SVG), you can drag and drop it as a graphic onto any page in GoodNotes & it does retain its vector lines. So while GoodNotes does not support SVG images, it does support vector images. It's just a matter of saving to the correct (.pdf) filetype in order to be able to use it in GoodNotes. Just about any quality graphic application can open an SVG file & from there you can save it as a PDF. Note: You cannot edit the vector image inside of GoodNotes — not even crop it. So, you must make all edits and crops before import. Here is video proof: https://youtu.be/7R3VI-kGenQ
