We’re preparing a paper for a Python package that supports igraph interoperability, and we’d like to include the igraph logo in a figure.
Similar to Fig 3 of the recent igraph paper (Antonov et al., 2026, PLoS One, igraph 1.0 enables fast and robust network analysis across programming languages ), showing the igraph logo alongside NetworkX and graph-tool logos to illustrate interoperability.
We found the logo files in doc/igraphlogo in the main igraph repository, but couldn’t find an explicit license or usage terms for them specifically
The homepage states code is GPL-2.0 and docs are GFDL. Could you confirm it’s okay to use the logo in a journal figure with a simple credit line (e.g. “igraph logo, © igraph core team”), or is there a preferred way you’d like it credited/licensed for this kind of use?
Thanks!
