In order to get started with Kiwi in no-time, we have created a bunch of demo data and connected a Tableau Server to try everything out.
You DO NOT need to connect your own Tableau Online or Tableau Server in the first place. After signing up via Slack or E-Mail all is set up and ready to go :)
Have a look at the Portal and Reporting pages.
By default, there is an active scheduled report that will send an update of some Tableau views every day. Just take it as an example and turn it off if you like.
To do that, go to Reporting select "manage" and "deactivate". The report will not send any more.
Once you connected your own Tableau and there is no need for the demo data, just delete it. Simply click "remove demo data" and it is gone :)
Have Fun with Kiwi.
