Rise: Issue with an iframe
I'm trying to insert a grapic as an iFrame within a rise project. During the preview, the graphic works perfectly however when I export the rise course as a "Web" type, it does not work anymore. The graphic from the iFrame will not displayed - the screen stays white.
Here is the iFrame code:
<iframe src="//datawrapper.dwcdn.net/fiywI/1/" scrolling="no" frameborder="0" allowtransparency="true" width="600" height="400"></iframe>
The URL for the iFrame graphic is here: https://www.datawrapper.de/_/fiywI/
What do I wrong?
