Annotation

Concerned with explaining things

What is the right amount and type of hep your viewers will need when consuming the visualization

Most neglected layer of visualization anatomy

Least amount of pure design thinking

Conforms to the Goldilocks principle

Too much and the display becomes cluttered, overwhelming and potentially unnecessarily patronizing

Too little and the viewers have to find their way around the visualization and thus forming their own understanding

Typography

Typography deals with text (How it will look?)

Typeface is a designed collection of glyths representing individual letters, numbers and other symbols of language based on a cohesive style

A font is the variation across several physical dimensions of the typeface such as weight, size, condensation and italization.

Typeface can have one or many different fonts in its family.

Type effectively represents the collective appearance formed by the choice of typeface and the font.

Serif typefaces add lines at the end of letters and symbol examples Garamond

Mainly used for print display

Sans-serif add no extra lines/stokes to characters example Verdana

Labels, title and screen display.
