It would probably be a bad idea to embed this in a web page just for technical reasons, but for avoidance of doubt: fonts that you have to buy licenses for are virtually never embeddable directly. As a rule of thumb, if a technically capable person could in a short amount of time recover the original font from your web page and use it in their own work, you're materially violating the font's license.

This isn't just how this graphing font works; it's how virtually all professional typefaces work.
