switch from PNG to PDF

[sreichl]

consider switching from PNG to PDF for all visualizations? TBD

Utility lost?
Size difference?

Pro: theoretically directly usable for figures ie manipulatable using illustrator or Inkscape

Scatter plots as PNG if more than X points (otherwise size explosion).

• Kick off discussion with collabs & AI

PDFs sometimes look weird when dragged and dropped into powerpoint in my experience
