Makes biology pathway diagrams as one finished PNG for a post, lesson, slide or poster: clean vector-style textbook illustration in violet, teal and amber with a crisp sans. The drawings come from a picture model and every word is set in real type on top, so labels are always spelled right. Best as a flow from intake to effect; other layouts work too. Needs a FAL_KEY or a Cloudflare Workers AI key; about $0.01 to $0.02 a drawing. Use when someone wants a pathway diagram, a "how it works in the body" picture, or an explainer of how a nutrient, drug or compound acts.

About this skill

You say

Make a pathway diagram of how vitamin D is made in the body

It said back

I made the diagram. It's a five-step flow, left to right: sunlight hits skin → into the blood → liver step → kidney step → calcium for bones.
