Labeling Individual Columns, Line Points, Etc.

Hello!

I’m attempting to label individual columns, line points, etc. These are completed through annotations, I see in Google’s documentation. And it’s obvious how to style the annotations, but I cannot determine how to activate them in the first place. I’ve tried simply adding the styles to chart_annotations as well as within chart_series='{"annotations":"... but nothing yet has worked.

Thank you!
