Pitch decks encodes values as one idea per slide; a chart only if it is the sentence. Sequoia/a16z memo culture plus Keynote-era startup theatre.
In reports, ads and assignments it fits fundraising, sales kickoffs, grant talks, competition finals. Skip it when dumping the whole dashboard — a deck is a speech, not a warehouse.
Mistakes

Pitch decks: honour one idea per slide; a chart only if it is the sentence, and switch when dumping the whole dashboard — a deck is a speech, not a warehouse.
