I am writing a book chapter in theoretical computer science. I would like to add figures based on figures previously published in relevant papers.
In the caption of each Figure I will cite the original source. Obviously, the figures that I will include are not the original ones but are made by myself.
However, since the figures are explaining abstract proof concepts there is not much freedom to make them really different from the originals apart from minor changes.
Am I still at risk of legal retaliation from publishers?
