A scarab chart for visualizing mass patterns in light-hadron multiplets

Particle charts are useful teaching tools, but the usual quark-model multiplet diagrams emphasize symmetry labels more than mass ordering. This paper presents a compact ``scarab chart'' for light hadrons that keeps the familiar isospin and hypercharge information while adding a mass-sensitive ordering. The chart is intended for modern physics or introductory particle physics teaching. Each tile represents a light meson or baryon, with columns labelled by isospin projection, rows ordered by an integer pion-anchored mass count, tile colour identifying hypercharge, and border colour corresponding to the pseudoscalar nonet, vector-meson nonet, baryon octet, or baryon decuplet. The chart is proposed as a pedagogical visualization. The result gives students a single visual diagram in which quark content, multiplet, strangeness, and approximate mass scale can be compared.
