Function Mapping Diagram - Visual Representation of Input-Output Relationships #2017985 (License: Personal Use)

This minimalist diagram depicts a foundational concept in mathematics and computer science: a function or mapping. Three orange circles (inputs) sit above a black horizontal line (the function rule), with vertical lines connecting them to two orange circles below (outputs), showing a many-to-one relationship. The clean, uncluttered design emphasizes conceptual clarity over technical detail.

Used in educational web pages, textbooks, or developer documentation to explain functions, relations, or data transformations. Matches user intent for visual learning of abstract concepts like domain/range, injective/surjective mappings, or database joins.
