The infographic is not very clear, but as far as I understood:

In the Podesta - Emails, there is an Email to Podesta about a "film project"; See here: https://wikileaks.com/podesta-emails/emailid/1459 (and to satisfy my paranoia: https://archive.is/uiFqE))

The hypothesis is that the film project is code for the assassination.

I know practically nothing about Scalia's death (except that the official version has been disputed), can anybody clear it up and explain whether Podesta had a motive?
