The only dependency the panel-vegafusion python package has to vegafusion python packages is the import of the vegafusion_jupyter.runtime.

The runtime is an instance of the VegaFusionRunTime defined in vegafusion_jupyter.

I believe its more natural that the VegaFusionRunTime is defined in the vegafusion package. In that way integration libraries have a more simple and natural dependency.

If not it would make sense for me to copy the VegaFusionRunTime implementation to panel-vegafusion package and drop the dependency on vegafusion_jupyter.

Please let me know what you would prefer @jonmmease ? Thanks.
