Open table in Voyager option producing incorrect data

This issue concerns the Open Table in Voyager option.

Here is the code to reproduce this issue.

Currently, with the code from above, I get this result when I right click the pandas dataframe and click the Open Table in Voyager option.

The data for the related views is not correct, and should look more like this, (just open cars.json with Voyager)

As you can see, the charts are different in that the data is inconsistent between the two, which should be the same! For instance, the Origin vs Number of Records barchart displayed from the pandas dataframe route is different than the one from opening a json file in Voyager

Good catch!

^^^ I think this is a general design question that Jupyter needs to answer properly.

I guess a big aspect of this is how you communicate the data from Python/R/whatever objects to the frontend in javascript and had thought arrow might fit the bill there.

IMHO It would be great if the Open in Voyager context menu could be integrated with the variable inspector. They’re already doing something similar by providing a phosphor datagrid view for numpy arrays. Although it’s not yet an officially supported extension I think it would make sense for it to be in future - it’s one of the highest request items from my users.
