Visualizing Otel data

[rogeralsing]

I'm working on a visualization tool for Otel data.
(https://github.com/asynkron/TraceLens for anyone interested)

Yesterday I tried it on the OpenTelemetry Demo application.

I would love to hear some feedback on how you think this matches the actual architecture of the various services.

Operation level details:

I also have a question regarding the Kafka part of the demo app.
Does it lack instrumentation when publishing to Kafka?
I see the Publish action as a span. but there are no parent spans leading to it. I would have expected one of the services to have generated a span that leads to the Publish action.

I'm both happy you did this and sad you did as well since you exposed an ugly truth about the Otel demo and the instrumentation-fs library with NodeJS that we should address.

This entire section in the frontend box should not be there. I'm certain there are options we can do to make that happen.
