The Iceberg Chart meme format serves as a visual representation of how knowledge about a specific topic is tiered, ranging from 'the tip of the iceberg' (mainstream information) to the 'abyss' (obscure or disturbing facts). This format gained massive traction on platforms like Reddit and 4chan, where users would compile deep-dive lists on everything from video games to true crime. By visually separating common knowledge from deep-web secrets, the meme highlights the rabbit holes enthusiasts fall into. It has evolved into a popular YouTube subgenre, where creators narrate each layer, turning simple charts into comprehensive video essays.
