How to Cite Info Used in a Self-Created Visual

[comatrip1]

I want to create a visual for a book I'm writing. The visual will be of my own creation, utilizing information that obtained from a source, but that wasn't aligned ion a visual like I need for my purposes. How do I cite the resource from which the visual is derived? Do I add a "copyright 2020 <insert source here>" or is can I simply say "derived from <insert source here>"? Thanks in advance!
