The simple page is accessible via <datacenter_url>/simple (for example, http://127.0.0.1:5700/simple), and provides a minimalistic UI that allows the selection of endpoints through the pre-configured tags (see Creating Datasets).
Tags can be selected directly through the UI or passed as an argument in the URL (for example, http://127.0.0.1:5700/simple?tags=Viz%20Libero,ShotMap).
If the tags are passed in the URL, the Tags column is not shown and only datasets relevant for the given tags are available for selection. If, given the tag filtering, only one dataset is available, it is automatically selected.
