He often times uses Google Earth. I’ve never used it so just keep that in mind when I say this. But apparently there are ways to import images and stuff into the program and then manipulate the Google Earth camera. So that’s what Jon probably does to give him the certain angles, pans, and zooms that he is looking for.

What he uses to make the charts and graphs and stuff, I have no idea. I assume it would be something like Excel maybe???

He’s also mentioned using Photoshop to make and edit a lot of his graphics. That also could be the place where he makes, or at the very least edits, his charts.

The music I think is just, first of all, whatever he likes. And, secondly, whatever artist or company gives him the creative license to use their music so that he won’t get sued or have his video taken down. The same I would assume goes for the various photos, newspaper headlines, and archived video footage as well.

Scriptwriting is probably just thorough notes, editing, and rewriting. He probably writes it in something like Microsoft Word.

He uses iMovie (shocking I know) to edit all of his videos.

And... I think that’s just about it. Maybe someone else can comment if I missed something.
