Morphology

fill + in

The sense of adding shading is a literal instantiation of 'fill' (to make something full by adding contents) combined with 'in' (into/inside), so the meaning of putting color or lines into areas is directly derivable from the constituents. This is a common, compositional phrasal-verb pattern and is cross-linguistically transparent, so a B1 learner who knows both words would likely understand it.

Etymology

Fill in for information comes from the idea of filling the empty parts of a story or a conversation; you put facts into the missing spaces to make the story whole. That's why to 'fill in' someone means 'to give someone the necessary or recent information'.
