I want to create a dashboard at work. Due to company restrictions, our best bet is to create one in SharePoint. This means we have to extract the data from an Oracle DB and use the data to create the graphics part, in
d3.js or something similar.
The problem here is that I can't figure out how to introduce HTML or any kind of scripting into a SharePoint page. I thought embed would do it, but apparently that only works for iFrames. I searched for tutorials but they are all from previous versions of SharePoint. Then I stumbled across a page in which it was said that removing the possibility to add HTML to pages was one of the changes for 2018.
Is there any way I can turn this around or I have to find a different mean to do this?
