A useful diagram starts with a question your reader needs answered. Before writing a long prompt, decide whether the drawing should explain a process, a system, a relationship or a comparison. Then provide the smallest set of facts needed to answer that question accurately.
Start with a scoped brief
Name the audience, the subject and the main question. For example: “Show a new teammate how a request moves from intake to approval.” Supply the steps and decision rules you know. If the information lives in a document, select the relevant section instead of asking for an unspecified summary.
Diagram types explains which format fits order, hierarchy, system structure and time. Image inputs and PDF inputs need different source checks.
Send, then check the first result
The first message opens a conversation workspace. If an important fact is missing, clarify it before treating the drawing as finished. Compare each label, number and connection with your source. Trace at least one ordinary path and one exception.
A diagram that looks polished can still be wrong. Do the structural review before spending time on color or spacing, and distinguish facts you supplied from suggestions the agent introduced.
Make one meaningful revision
Describe the change and the constraints that must stay intact. “Add a legal review after approval and keep the existing revision loop” is easier to verify than “Make it better.” For a small correction, edit a supported label or position directly. Use the conversation when the change affects several connected elements.
Reopen the prior version if a revision changes more than intended. For a set of related diagrams, check that the same participant or component has consistent naming across all views.
Prepare the handoff
Choose PNG for an image in a document, SVG when the graphic needs to scale, PDF for a page-based deliverable or HTML for a browser view. Review the selected saved version before exporting. A read-only sharing link is useful when the recipient needs to view a result without receiving the conversation or source files.
