Dear all,
The new SBGNview package has been released with major updates and improvement:
GitHub
https://github.com/datapplab/SBGNview
BioC
https://bioconductor.org/packages/SBGNview/

SBGNview is a tool set for pathway based data visualization, integration and analysis. SBGNview is similar and complementary to the widely used Pathview package, with the following key features:
• Pathway definition by the widely adopted Systems Biology Graphical Notation (SBGN);
• Supports multiple major pathway databases beyond KEGG (Reactome, MetaCyc, SMPDB, PANTHER, METACROP etc) and user defined pathways;
• Covers 5,200 reference pathways and over 3,000 species by default;
• Extensive graphics controls, including glyph and edge attributes, graph layout and sub-pathway highlight;
• SBGN pathway data manipulation, processing, extraction and analysis.

You may find an overview and quick start examples here:

Please try it out and let us know if you have any comments/suggestions. Thank you!

To install and use the latest updates of SBGNview via BioC, i.e.

BiocManager::install("SBGNview")

users may need to first update to the current Bioconductor release version 3.12 or devel version 3.13.

Note SBGNview works with major pathway databases other than KEGG
pathview focuses on KEGG
