Part 2. How to Write Top Flowchart Prompts

Why Flowchart Prompts Matter

Creating effective flowcharts isn't just about listing steps. A well-crafted prompt captures decision points, parallel processes, and exceptions clearly, helping AI understand how your process flows. Think of your prompt as explaining your process to a colleague who has never seen it before.

Key Elements of Effective Flowchart Prompts

• Start with the big picture: Define the process scope and objective. For example, "Create a flowchart for customer onboarding from signup to first product use" is clearer than "make an onboarding flowchart."
• Include decision points: Highlight branches like "if payment fails" or "when approval is needed" to create useful decision nodes.
• Specify actors and handoffs: Indicate responsibility shifts, e.g., "Sales qualifies the lead, then hands off to Customer Success."
• Mention parallel processes: Clarify simultaneous steps, e.g., "While the legal team reviews the contract, the technical team sets up the account."

Use the RTCF Framework to Structure Prompts

• Role: Who you want the AI to act as
• Task: What outcome you need
• Context: Background information that matters
• Format: How the flowchart should be structured

Part 3. Best 50 Nano Banana Pro Prompts for Flowchart

Here is a structured, comprehensive list of 50 prompts designed to get the best flowchart results from Nano Banana Pro. To maximize utility, I have designed these prompts to request Mermaid.js syntax (a standard text-to-diagram format) or structured logical steps. You can copy and paste these directly.

Pro Tip:

For all prompts below, if you need a visual code output, append this phrase to the end of the prompt: "Output this as a Mermaid.js flowchart code snippet."
