Is your feature request related to a problem? Please describe.

OTTL is a compelling way to provide adjustments without custom processors. As far as I know, someone can test ottl by running a collector with the transform processor.

Especially to those coming from different backgrounds, with different languages in mind, we may benefit by lowering the barrier to experimentation. Go playground comes to mind as a popular way to get started with the language, without any install

Describe the solution you'd like

I'd like to see something like Go playground for OTTL, which runs in the browser (perhaps by compiling certain ottl code to wasm). Ideally, everything is client side, and they can post their own signals (e.g. a trace) and practice transformation results. We could host the assets somewhere public as well.

Describe alternatives you've considered

Alternative could be to make an installable tool that eases the same, or just add a section to the README saying how you can most easily experiment on this.

I like this idea. If someone is willing to take on the work I think it would be useful.
