Graphana use cases other than APM

Hi guys,

I have recently found out this great application. Unfortunately I had never heard about Graphane before. From most of the explanatory videos showing how does graphana work are based basically on application monitoring use case. Is it possible to use Graphane for another use cases - like monitoring sales performance, learning progress of students etc. ? We have completely another use case like these where store calculated measurements in postgres db. We have currently our own builtin graphs developed for our web application which we are interested in to switch to an other solution which could help us flexibly scale and offer more flexible features to our users/customers.

Thanks,
