The Anatomogram package provides an interactive, React‑compatible visualisation of organism‑level anatomy (human, mouse, plant, etc.) that highlights tissues based on expression data from the EMBL‑EBI Expression Atlas. It ships as an npm module exposing a `<Anatomogram/>` component (or a plain `render` function) and lets developers colour, select, and attach callbacks to individual anatomical regions using Uberon/EFO/Plant Ontology identifiers, making it useful for bioinformatics web tools that need to display tissue‑specific expression results.
