Please consider a feature to integrate the Mixpanel data directly into pandas library for analytis/visualization/modeling?
You can consume the Mixpanel analytics data using the Data Export API.
An example of receiving data using Python can be found here:

You can then use Pandas as you normally would, for analysis/visualization/modeling.
Hope this helps.
