Display is blank

I feel this is user error, but I can't see any place to ask questions other than here.

No matter how I run vaping, I seem to end up with a 'blank' webpage:

I've tried running it in a container using virtual environments, and as a docker image, but the results are the same. This is using the included config examples.

When I run in debug mode, it looks like it is collecting data:

Interestingly, I get what I think are errors when running the docker version:

I happened upon the same symptom trying to run on Ubuntu 24.04. If you look at the graph_data requests in Chrome debug panel under Network, you might see a relevant error. Mine were getting the error response {"meta": {"error": "module 'inspect' has no attribute 'getargspec'"}, "data": []}.

Python >= v3.11 deprecated getargspec, so if your system has >= v3.11, you'll need the change here to fix. https://github.com/20c/vodka/pull/23/files

Thanks, that fixed it
