Setup Tempo in Grafana (Newbie Question)

Hi all,
Some questions about setup Tempo from a newbie (me) :slight_smile:

I manage to connect to the tempo data source in Grafana as below.

In terms of the tracing in tempo, how could we see the tracing graph in Grafana?
I tried to query something in there but seems like nothing I could see so far.
Do we have any template to download so we can setup the tracing map right away?

Kindly see if anyone could provide some documentation or steps so I can follow and achieve the tempo setup further. Many thanks.
