"The purpose of writing is to inflate weak ideas,
obscure pure reasoning, and inhibit clarity.
With a little practice, writing can be
an intimidating and impenetrable fog!"
This prompt is about diagrams. So I found some examples to give you ideas for your journal pages.
I've been intrigued by diagrams since I was very young. I love the intricacies, the notes, the little sketches, the legends, keys, labeled components. Use a diagram in your art journal. You can create the diagram in pencil, ink or marker or cut out a diagram from an old textbook, magazine, etc. The topic could be something that you would like to learn about or perhaps an area of expertise that you would like to document or share.
