An infographic says “12 books returned,” but the source lists eight morning returns and four afternoon returns. Before sending the image, make sure the heading, total, categories, and source note all describe that same measure. Download the visual only after its words and numbers agree with the source material.
Google's current help page calls this feature an Infographic in Gemini Notebook. If you searched for “NotebookLM infographic,” use the product's current controls and the account you are permitted to use; do not move source material into another account just to expose a missing option.

Generate and download through the notebook
Google's infographic instructions say to open a notebook with sources and choose Infographic in Studio. Edit access is needed to generate or delete one, and the help page currently limits the feature to users over 18. The pencil icon opens preferences including language, detail, orientation, style, and a custom prompt.
Once generated, the three-dot menu offers a PNG download. Google warns that the visual may contain factual or visual inaccuracies. Open the downloaded file and compare its labels and values with the original sources rather than assuming the export step verifies them.
Specify the picture before asking for a design
Here is a small original fictional source set for a book-return activity. It is a checking exercise, not a real library report:
Source B01: Morning session — 8 books returned.
Source B02: Afternoon session — 4 books returned.
Measure: books returned, not unique borrowers.
Activity date, location and collection method: not supplied.
The total for these supplied sessions is 8 + 4 = 12 books. The morning share is 8/12 and the afternoon share is 4/12. A graphic labeled “12 readers” would change the measure; the notes do not contain a borrower count. A label saying “all daily returns” would also introduce a scope the source does not establish.
The complete example provides an author-drawn graphic, its exact source rows, and a plain-text explanation. It was not generated or exported by NotebookLM. Use it to practice comparing a picture with source values before checking your own actual export. Its full local HTML includes the original SVG artwork.
Copy a source-bound infographic request
Create an infographic from the selected notebook sources.
Audience and question: [SUPPLY]
Exact source passages, record names and units: [PASTE]
Permitted period and scope: [SUPPLY]
Required labels and attribution: [SUPPLY]
Use only supported values and preserve their units. Distinguish a
count of items from a count of people. Do not invent a date, a whole-day
total, a trend or a cause. If a calculation is needed, keep the input
values and the arithmetic visible in the source note. Use a readable
layout with enough room for labels. Mark missing information explicitly.
For B01 and B02, a suitable custom request would ask for two labeled bars, a 12-books total, and a note that the figures refer to the supplied morning and afternoon sessions. The exercise's bar values and arithmetic are author-created choices, not a prescribed Google layout.
Choose the handoff that matches the reader
Google documents both sharing the notebook or infographic link and downloading the image. Its link instructions require notebook access and full-notebook viewer access; public sharing is described for consumer accounts and disabled for Workspace Enterprise or Education accounts. Publisher restrictions on a Play Books source can also limit artifact downloads. Check the route available for the actual notebook.
If the reader needs only the checked visual and you may distribute it, send the actual PNG with a concise source explanation. If they need to inspect the notebook, use the notebook's authorized sharing route. A downloaded image and notebook access are separate handoffs.
For a browser reading copy, keep the picture beside a text explanation of the quantities and the source scope. The images of text guide explains why ordinary information should remain available as adjustable text. Do not make a tiny source label inside the picture the only place the reader can find the measure.
An interactive infographic is a separate HTML output with interactions. Downloading a PNG does not turn its bars into filters or recover hidden details. Open the file you intend to send, read every label, and confirm that its total still means what the source says.
