What is an simple logging aggregator?

I'm running a NodeJS server that currently prints nice logs to the console using the `debug` package. As the server gets more busy, I would like to print my logs as pretty graphs (N users on the platform at Y time, etc.)

It seems like the correct thing to use is Grafana + Loki, or something like the elastic stack. But these are far too heavyweight. Is there some dead simple solution I can use to visualize my logs well.

Anything that runs in a docker container should be OK.
