iFrames allow you to embed one website into another. iFrames are great for referencing large files, like YouTube videos or, in this case, 3D rooms. You can display the info without hosting it, which also means you can keep your site's load time fast.
Imagine a Sagan iFrame as a little window into your Saganworks. Create and host your room in Saganworks, then reference it via an iFrame you've generated. As an example, here's the iFrame for the embedded Sagan above:
<iframe style="width:100%;height:550px;border:0" src="https://app.saganworks.com/public/61911ad6-034e-4977-99ac-08d8a103650b" allowfullscreen=true ></iframe>
Paste the code into the html portion of your website editor. Adjust the height of the 'window' by changing the number of pixels.
