Even if it is in beta, and has some quirks around resizing the overall display - I did a proof of concept pretty quick, I drew the background in InkScape and then exported as PNG for the background, placing the data is just drag and drop - it seemed to only want to allow me to pick data from the first query, but I did a transform in Grafana to join the three values into one table, which it liked better.
In the demo they have animated wiring, trying to figure out how they did that - ie as minimum the lines connecting the circles should indicate flow direction, but animated is the goal.
