Visualizations based on the Dust and Magnet metaphor aim to present the information of the reduced dimensions via interactivity, while also supporting user comprehension by using a metaphor of ferrous dust and magnets. We compare two approaches to implementing this metaphor into a visualization tool along a set of core visualization tasks and propose extensions to make such visualizations more comprehensible and less misleading.Attribution 4.0 International LicenseCCS Concepts: Mathematics of computing → Dimensionality reduction; Human-centered computing → Visualization systems and toolsMathematics of computing → Dimensionality reductionHuman centered computing → Visualization systems and tools10.2312/evp.202511403 pages
