How to update the font-family in the center of a pie chart?

Problem:
I'm trying to update the font-family in the center of a pie chart but it won't update. How do I go around this?

Solution:
Styling your font within the globals: {} tag will be the easiest and quickest way to style your fonts. You see the word global and can visually make the connection that changes here will be made to all text across the whole chart. Please use this demo for reference.
