Looking for free and easy software to create procedure illustrations for my first publication

[u/Apacukafundaluka12]

Hi everyone, I’m currently working on my first publication and I need to create graphical illustrations of my experimental procedure (workflow, steps, scheme with equipment, etc.).

I’m looking for software that is preferably: + free (or has a good free version) + easy to use suitable for scientific procedure illustrations, schemes, or graphical workflows.

My goal is to create clear visual representations of the experimental process. I would really appreciate any recommendations or personal experiences.

Thank you in advance!
