  Summary: The Systems Biology Markup Language (SBML) is an extensible standard
format for exchanging biochemical models. One of the extensions for SBML is the
SBML Layout and Render package. This allows modelers to describe a biochemical
model as a pathway diagram. However, up to now there has been little support to
help users easily add and retrieve such information from SBML. In this
application note, we describe a new Python package called SBMLDiagrams. This
package allows a user to add layout and render information or retrieve it using
a straightforward Python API. The package uses skia-python to support the
rendering of the diagrams, allowing export to commons formats such as PNG or
PDF. Availability: SBMLDiagrams is publicly available and licensed under the
liberal MIT open-source license. The package is available for all major
platforms. The source code has been deposited at GitHub
(github.com/sys-bio/SBMLDiagrams). Users can install the package using the
standard pip installation mechanism: pip install SBMLDiagrams. Contact:
