Depending on the needs for information analysis, several cards will have to be created. We must first create cards individually, before we can incorporate them into a page.
You can review all the information in the Cards section to see all the possibilities you have. In general, the data card editor is used to configure the queries and the final visual customization of the card.
Remember that cards and pages are stored in spaces (either your personal space or a shared space), so you have to navigate from the list of spaces to the desired space. If necessary you can create a new shared space to work with these cards and pages.
