Saturnino Luz, Masood Masoodian

TL;DR
This paper explores the use of mosaic diagrams for visualizing set relationships, comparing their effectiveness to linear diagrams in terms of accuracy, speed, and user perception.
Contribution
It introduces mosaic diagrams as an alternative visualization method for set relations and evaluates their performance against linear diagrams.
Findings
Mosaic diagrams perform similarly to linear diagrams in accuracy and speed.
Participants rated mosaic diagrams as equally easy to interpret as linear diagrams.
Mosaic diagrams are a viable alternative to traditional set visualization methods.
Abstract
We present an application of mosaic diagrams to the visualisation of set relations. Venn and Euler diagrams are the best known visual representations of sets and their relationships (intersections, containment or subsets, exclusion or disjointness). In recent years, alternative forms of visualisation have been proposed. Among them, linear diagrams have been shown to compare favourably to Venn and Euler diagrams, in supporting non-interactive assessment of set relationships. Recent studies that compared several variants of linear diagrams have demonstrated that users perform best at tasks involving identification of intersections, disjointness and subsets when using a horizontally drawn linear diagram with thin lines representing sets, and employing vertical lines as guide lines. The essential visual task the user needs to perform in order to interpret this kind of diagram is vertical…
