Inverted pyramid

The inverted pyramid typically refers to a graphical metaphor that illustrates how information should be arranged or presented within a text, in particular within a news story. Despite the name, almost always the figure is drawn simply as an equilateral triangle with an apex pointing downward, rather than as a three-dimensional pyramid in perspective[?]. The triangle's broad base at the top of the figure represents the most substantial, interesting and important information the writer means to convey. The triangle's orientation is meant to illustrate that this kind of material should head the article. The tapered lower portion illustrates that other material should follow in order of diminishing importance.

The hourglass[?] is another figurative paradigm for text construction.
