quickstart issues about jaxpr-viz

Thanks for trying it out!

But no output is created.

Apologies this is the README being a bit unclear! jpviz.draw(bar)(jnp.arange(10)) returns a pydot graph object which then needs to be visualised (see here https://github.com/pydot/pydot#output). So the end of the example should probably be something like

import jpviz

dot_graph = jpviz.draw(bar)(jnp.arange(10))
dot_graph.write_png("computation_graph.png")

which will render the graph and write a file. I'll extend the README to make this clearer.

Here I get the error FileNotFoundError: [Errno 2] "dot" not found in path.

This is normally due to graphviz not being installed on your system. Though if you do, it could be something like this issue where conda environments need a conda install of graphviz? Pydot suggests you should usually be able to install using system package manager.

Closing as seems the issue was the missing graphviz install
