Definitions

  1. A visualization technique that represents hierarchical data as nested rectangles, where each rectangle's area is proportional to a quantitative value. Commonly used to display disk usage, bundle sizes, or stock market sectors at a glance.

    In plain English: A chart made of nested rectangles where bigger rectangles mean bigger values, useful for seeing which parts take up the most space.

    Example: "The webpack bundle analyzer treemap showed that moment.js locales were taking up 40% of our JavaScript payload."
