Free AI chart maker — for exact charts, not guesswork
You should not have to fight axis labels and legends to get a chart that matches your numbers. Paste a CSV or type your numbers into Gixo Prism's Chart Maker, and it renders an exact chart — structured chart controls, with display precision and source data to review.
Start free — 14-day trial Open the chart maker
Prism public chart makers render and preview without an account and offer attributed HTML/SVG output. Choose supported structured inputs, review the layout and display settings, and export an appropriate format. Clean exports of an unsaved preview and new saved-work actions have their applicable access rules. A 14-day no-card trial runs at Starter level; Brand Kit requires eligible Professional-or-higher access.
Why does a deterministic chart maker beat manual charting?
No dragging legends, no fighting axis scales, no chart that quietly disagrees with your data.
No manual axis or legend work
Paste your data and the maker positions axes, labels, and legends for you. You do not touch a single handle.
Exact values, drawn from the accepted values; display labels can round according to their settings
There's no AI image model in the loop. Your numbers are rendered directly to SVG, so what you entered is exactly what shows up on the chart.
Brand-consistent theme, every time
Pick a theme preset or your Brand Kit palette once. Every chart you generate after that matches it automatically.

Frequently asked questions
Do I need design skills to use this?
No. Paste a CSV or your numbers and the maker handles axis scaling, labels, and legend placement. You only decide what to chart.
Is this fully free?
Public maker rendering, preview and attributed HTML/SVG remain available without an account. A clean export of an unsaved preview needs eligible access; an owner can download a saved maker revision without a current generation plan.
What chart types are supported?
22 renderable types — bar, horizontal bar, stacked bar, line, area, pie, donut, scatter, radar, waterfall, funnel, Gantt, bar-and-line combo, heatmap, treemap, symbol map, Marimekko, bubble, Sankey, bullet, slope, and dumbbell — plus an auto mode that picks the best type for your data shape.
Can I apply my brand to the chart?
Choose a built-in theme preset. Applying your saved Brand Kit requires eligible Professional-or-higher access; it is not part of the Starter-level trial. Review the actual palette, typography and exported output.
Does the free trial expire?
Yes, the no-card trial runs for 14 days at Starter level. Public rendering and attributed HTML/SVG remain available after it ends; new saved work and clean exports of an unsaved preview have their applicable access rules.
Is Gixo's chart maker really free, or is it a trial?
Public maker rendering, preview and attributed HTML/SVG are available without an account. Clean exports of an unsaved preview need active Prism access. A 14-day no-card trial runs at Starter level; owners can download saved maker revisions without a current generation plan.
What export formats are supported?
The maker exports HTML, SVG, PNG, PDF and PPTX. Attributed HTML/SVG is public; clean exports of an unsaved preview need active Prism access. Compatible PowerPoint charts and native shapes have different editability; inspect the file you will hand off.
Will my numbers ever get rounded or changed by the AI?
The maker draws accepted structured input without an AI image model. Display settings can round labels, crop axes or shorten text, and shape/input limits apply. Review warnings and compare the rendered result with its source.
