Add support for embedding Desmos graphs on your page!
Create graphs at http://www.desmos.com/. Once complete, sign in to save your graph. Use the "Share Graph" button to create a shareable link. Copy the last part of the link and paste it as the "Desmos ID".
For example, if your after clicking "Share Graph", you are given a link to "https://www.desmos.com/calculator/vtg4yofu3f", then your Desmos ID would be vtg4yofu3f.
Please note, I am NOT a Desmos developer, and cannot help you with problems with Desmos. I've only created this Weebly app so that you can embed Desmos graphs to your page easily.
