Check Nano Banana Pro diagrams before publishing

Image generation can help with drafts, while text, facts and relationships still need review.

Google introduced Nano Banana Pro, also called Gemini 3 Pro Image, on November 20, 2025. Its announcement described image generation and editing, improved text rendering and uses such as diagrams and infographics. [1]

The original post resurfaced the release later. Keep that November date attached to the announcement rather than treating every repost as a new model launch.

Verify the content before the styling

Write the facts and labels you want the image to communicate first. For a diagram, define the relationships in plain text before asking for an illustration. Then compare the generated result against that description.

Read every label at the size readers will actually see. Check numbers, units, arrows and whether the picture implies a relationship you did not intend. Clear lettering does not guarantee correct information.

Keep essential explanations in HTML alongside the image so readers can select the text and use assistive technology. Add alternative text for the image's purpose, and export an appropriately sized file for the page.

Use the generated image as a reviewed illustration, not as the only copy of important information.
