User Sharepoint List with graph

Hello;

Thanks for your answer v-chuncz-msft.

But how is it possible to have graph by SharePoint user ?

Create a role by user / but if I have 200 users and I do not know who is connected ?

And how is it possible to create the filter in function user connected so that he only sees his data ?

I would like to use this graph in a powerApps application and depending on the connected person he only sees his graph with only his datas.

=> Generic graph AND when a person connects to the application => modifie graphq with his data /[ it's possible ?  :s ]

Thanks for your help ! :)
