Generated crystallographic tables
----------------------------------
data/spacegroups.json and data/layergroups.json are generated by
tools/gen_groups.py using PyXtal (MIT License). PyXtal's symmetry tables are
described by its maintainers as derived from crystallographic sources including
the Bilbao Crystallographic Server. Users of these data in research should cite:

Element display data
--------------------
data/elements.json and materia-io/src/radii.rs are generated with pymatgen
(MIT License) from its periodic-table radii and Jmol/VESTA color tables. Cite:
