ggPSE: Periodic Table Visualization Using ggplot2

A ggplot2-based toolkit for visualizing data on the periodic table of elements. Supports continuous color gradients, bubble size encoding, selective element highlighting, per-group or per-period plots, per-element charts and country-of-origin badges. Returns ggplot2 objects that can be further modified with standard ggplot2 syntax, including faceting and custom themes. Developed with AI assistance from Claude (Anthropic, 2026).
