I'm trying to embed Jsmol viewer (a program to view molecules in 3D) into my Canvas page.    I have tried using iframe but it comes up with an error that says the website refused to connect.  I also tried to embed it using the code (shown below) given on the Jsmol page, but it just shows up blank.   

<script type="text/javascript" src="https://chemapps.stolaf.edu/jmol/jmol.php?model=acetone&inline"></script>

Is it Canvas that is blocking it to work?  Any help would be greatly appreciated.
