Visualize Values as Graphs

Is there any way to visualize values from modifiers (or really any source) in a graph? For example if I use the Smooth Envelope over a Sound modifier, I would like to see what effect it has in a graph. I read about the Graph Geometry node, which seemed to have exactly that function, but apparently it doesn’t exist in 0.9.23. Was this somehow replaced by another node? Or am I completely missing something here?

Just starting out, so I’m really thankful for any tips!
