There is one failure in this category that matters more than every other consideration: image models generate charts that look like charts and contain invented numbers. The bars are not proportional to anything, the axis labels are approximate, and the whole thing is a picture of data rather than a representation of it.
Publishing that is not a design mistake. It is publishing false information in the format people trust most.
TL;DR
- Never let an image model draw your data. Bars will not be proportional and labels will be wrong
- Make charts in a chart tool, free ones are excellent, then design around them
- Where generation fits: layout, icons, illustration, section dividers, the visual language
- On 8frame: Nano Banana Pro at 21 credits when text in the image must be correct
- Check every number in the final file against your source
The proportionality problem
An image model has learned what a bar chart looks like. It has not learned that the bar labelled 40 must be exactly twice the height of the bar labelled 20. So it produces a plausible arrangement of bars with plausible numbers next to them, and the relationship between the two is decorative.
A reader looking at an infographic is reading the visual relationship, not the labels. If the visual says one thing and the data says another, you have misinformed them, and they have no way to know.
This applies to every chart type: pie segments that do not sum correctly, line trends that do not follow the values, scatter points in the wrong places.
The workflow that is actually correct
- Put the data in a spreadsheet. Verify every number against its source.
- Generate the chart in a chart tool. Free options are excellent and produce accurate, properly scaled output.
- Export the chart as an image or vector.
- Design around it. This is where generation helps: background, icons, section treatments, illustrative elements, colour system.
- Check every number in the final composed file against your spreadsheet. Numbers get lost in layout.
Where generation genuinely helps
Layout and visual language. The look of the piece, the colour system, the decorative structure.
Icons and illustrative elements. The small visual markers that make an infographic readable and scannable.
Section dividers and backgrounds.
Concept illustration. A visual metaphor for the thing the data is about, clearly illustrative and carrying no data itself.
Exploration. Twenty layout directions at 6 credits each, before building the real one.
What it costs
Canon 8frame prices, a credit is $0.01 at pack rate:
| Asset | Route | Credits |
|---|---|---|
| Layout or background direction | Seedream 5 | 6 |
| Element with exact text | Nano Banana Pro | 21 |
| Cheapest volume exploration | Imagen 4 Fast | 4 |
| Illustrative concept element | Reve | 34 |
| Adjust a generated element | Flux Edit (FLUX.2 pro) | 7 |
| Upscale for print | Topaz Image Upscale, per 24MP block | 11 |
A full infographic's visual layer: ten layout explorations (60), six icons or elements (126 on Nano Banana Pro, or 36 on Seedream 5), one upscale (11). Between about 110 and 200 credits, roughly $1.10 to $2.
The charts themselves are free in a chart tool, which is also the only place they should come from.
The design rules that carry an infographic
One argument. An infographic makes a point. If it contains three unrelated findings, it is three infographics.
Order by the argument, not by the data structure. Lead with the finding, support it, then contextualise.
Label directly. Legends make the reader work. Put the label on the thing.
Do not use a pie chart for more than three segments. People cannot compare angles.
Cite the source, visibly. An infographic without a source is decoration, and in 2026 readers increasingly assume the numbers are made up unless you show otherwise.
That last point is the opportunity: a sourced, accurate infographic stands out precisely because so much of what circulates is not.
FAQ
Can AI generate accurate charts? Image models cannot. They draw chart-shaped pictures with invented proportions. Use a chart tool.
What is the best free infographic tool? A free chart tool for the data, a free design tool for the layout, generation for the decorative layer.
Where does generation help? Layout, icons, illustration, backgrounds. Never the data.
How do I check my infographic? Read every number in the final file against your source spreadsheet.
Charts from a chart tool, everything else generated. The 8frame canvas is free and unlimited, and generation is paid from $19/month.
