The sample node representations found in the "People" palette section were created by a designer here at yWorks GmbH. Thus, the copyright owner of these images is yWorks GmbH. If you'd like to use the People icons in a publication, we would be very happy if you added a note along the lines of "This figure was created with the yEd Graph Editor application: https://www.yworks.com/yed" (near the diagram or in the references list, for example, when it's an academic publication). That would be great!
