I don’t like packages that require external access to function. I understand the business mode and think there are clear ways to do this (plotly and graphistry come to mind), but I don’t think the benefit outweighs the downsides to use these types of libraries.

At least this can be easily refactored out, plotly and graphistry don’t really function well without the api calls. Plotly offline exists, but trying to keep track of features between the two is a pain. And the reasoning given for the api (massive scale conpute) could be easily abstracted for local mode if they wanted.
