The details
Chapter 4 is adapted in anime episode 2. That episode also covers chapters 3–5, so it is not a one-to-one adaptation.
One Pace re-cuts the anime to follow the manga's pacing, removing filler and padding. This chapter appears in The Pirate King and the Master Swordsman.
Netflix's live action passes through this chapter in season 1, episode 1, which covers roughly chapters 1–7 in a single hour. That is a span rather than a chapter list on purpose — the show reorders and merges as it goes, so nobody can honestly map it panel for panel.
