Periodisk
Periodisk is an open-source Python package for generating accessible, source-traceable periodic tables for chemistry teaching. It produces SVG and PDF files using an offline dataset of all 118 elements.
Installation
Periodisk requires Python 3.13 or newer.
python -m pip install periodisk
Usage
Command line
The periodisk render command writes a periodic table to an SVG or PDF file.
The output format is inferred from the filename extension. For example, render
the default English table on an A3 page with:
periodisk render periodic-table.pdf --language en_GB --page-size A3
Run periodisk render --help for every option and its description.
Python API
The same table can be generated through the Python API:
from periodisk import render_table
render_table(
"periodic-table.pdf",
language="en_GB",
page_size="A3",
)
Periodisk supports:
- British English and Norwegian Bokmål (
nb_NO) - Detailed and simplified table content
- Detailed and broad element classifications
- Multiple accessible, print-oriented colour schemes
- Configurable cell styles and rounded corners
- Pauling, Allred-Rochow, and Allen electronegativity scales
- SVG and PDF output
