Oracle has a new (?) Oracle Cloud Infrastructure (OCI) Product Tours page: https://www.oracle.com/cloud/product-tours/
At the moment the Analytics section seems to be very active: https://www.oracle.com/cloud/product-tours/#analytics
I like the links to the YouTube videos.
See if you find anything interesting there.
If you are here, this is a reminder of the Analytics Live Demos page: https://www.oracle.com/business-analytics/data-visualization/demos/ where you can run a live demo (see arrow), download useful elements (Examples, Extensions, Geo Layers and Rest Connectors), add your ideas in Idea Lab and see Videos.
