Prepare the structure
Paste CSV/TSV or import an Excel workbook, choose its sheet and inspect the grid. Map categories and series, then check the shape required by the selected chart family.
AI Chart Maker
Paste a CSV or a few numbers and get a clean, data-exact chart from the supplied input. Gixo Prism's chart maker is deterministic, not an image model — the number you put in is the number that comes out, never a garbled AI value. Any of 22 chart types, from bar, line and pie to waterfall, Gantt and heatmap, rendered to crisp SVG and ready to edit.
An AI chart maker turns a pasted table or Excel worksheet into a finished chart without manual plotting. Gixo Prism's chart maker is deterministic rather than an image model, so the value you enter is the value rendered to SVG — no AI step redraws or garbles a digit. It covers 22 chart types (including bar in three variants, line, area, pie, donut, scatter, radar, waterfall, funnel, Gantt, combo, heatmap, treemap and symbol map), handles type-specific limits, with an expanded-data option, applies your brand palette automatically, and exports as HTML, SVG, PNG, PDF, or PPTX.

Read the sample review notes
Fictional demonstration data, not customer results. Check labels, units, branches and all supplied values before reuse.
Refine with meaning
Choose legible type, deliberate colors, labels and units. Brand bold is the default for new visuals, in the Bold colors until a saved Brand Kit applies; a saved or explicitly selected theme remains yours. Check figures against your source and inspect retained data after a chart-type change.
Inspect and share
Read the chart data table or diagram labels, add appropriate alternative text and inspect the actual export. Review and publication permissions are separate from clean-output download rights.
Data mapping, chart objects and accessibility
Inspect an imported workbook's sheet and cells, edit the data grid and choose series and category mappings. Chart-specific shape checks, axes, numeric formatting, labels and legends affect the reading. Review alternative text, long descriptions and the data table. A changed chart type can retain data that needs reshaping.
Graphs, compositions and connected data
Review nodes and branches, Mermaid interchange and saved revision comparisons for structured diagrams. Compositions can combine visual blocks with brand type and colors. Their editing tools differ from those used for structured charts. Connected data controls offer bounded filtering, sorting, column selection, row limits and supported calculated columns; inspect a refresh before accepting changed source values.
Campaign assets and print proofs
Campaign kits support channel choices, sized artwork, photos and crops, captions, selected-channel regeneration and review of edited copy. Print controls cover copy, layout, photo placement, fit, density and proof checks. Print supports English, Germanic, Latin, Cyrillic, Arabic, Indian, Chinese, Korean and Japanese language/script groups. Inspect the actual export and destination requirements.
Color and preflight options are checks with defined scope, not accessibility certification. Structured SVG editability does not imply that composed raster artwork has the same editing model.
A chart maker that gets the numbers right
Prism renders your data deterministically — same input, same exact chart, every time. No AI image step where digits get redrawn and garbled.
Paste a CSV
Drop in a CSV or type your numbers and labels. Prism reads the data straight into a chart — no manual plotting, no re-keying.
22 chart types
Bar, line, area, pie, donut, and scatter — the workhorse types that cover most business and report charts. Pick the one that fits the point.
Accepted values, reviewed display
The maker renders accepted chart inputs deterministically without an AI image call. Visible labels can round under the selected precision settings; review source values, units and label fit in the actual SVG.
Multi-series support
Compare several series at once — practical up to the selected type-specific limits, which keeps a chart readable instead of crowded.
Editable, re-renders exactly
Change a number, a label, or the chart type and Prism redraws after the update with the same fidelity. Edit as many times as you like.
On-brand colors
Prism applies your brand palette across every chart, so a set of charts in one report looks like it came from one team.
Clean HTML/SVG export
Export each chart as self-contained, scalable HTML/SVG you can drop into a deck, doc, or web page — or as PNG, PDF, or PPTX. Sharp at any size.
More than charts
The same exact-by-construction approach powers Prism's diagram, flowchart, and card makers — so a whole visual set stays consistent.

How to make a chart with the AI chart maker
From raw numbers to a finished, on-brand chart in four steps.
1
Paste your data
Drop in a CSV or type your categories, labels, and values. Prism reads them in exactly as written.
2
Pick a chart type
Choose among grouped, horizontal or stacked bars, line, area, pie, donut, scatter, radar, waterfall, or Gantt — whichever fits the relationship you're showing.
3
Edit and apply your brand
Tweak labels, swap the chart type, or adjust series. Prism keeps every value exact and applies your brand palette.
4
Export the chart
Take the chart as clean, scalable HTML/SVG into your deck, doc, or page — sharp at any size, with the data intact.
Why a deterministic AI chart maker beats an image model
When the numbers have to be right, how the chart is built matters more than how it's prompted.
- The wedge is determinism. Prism's chart maker renders your data with code, not an image model. The value you enter is the value drawn to SVG — there is no step where a model redraws digits and quietly garbles them.
- The 22 chart types cover comparison, trend, composition, relationship, bridge, and schedule work. Examples include grouped bar, horizontal bar, stacked bar, line, area, pie, donut, scatter, radar, waterfall, funnel, Gantt, bar + line combo, heatmap, treemap, and symbol map.
- The honest cap is the selected type-specific limits. Beyond that a chart gets crowded and hard to read; Prism is built for clear, presentation-ready charts rather than dense data dumps.
- Charts export as HTML, SVG, PNG, PDF, or PPTX. HTML/SVG is scalable and stays crisp at any size; chart PPTX comes through as editable PowerPoint content rather than a flattened image. In the PPTX, bar, horizontal bar, stacked bar, line, area, pie, donut, scatter, radar, and bar-and-line combo charts arrive as native PowerPoint charts with their numbers in an embedded workbook that Edit Data opens; waterfall, funnel, Gantt, heatmap, treemap, symbol map, Marimekko, bubble, Sankey, bullet, slope, and dumbbell charts arrive as editable PowerPoint shapes and text, as does any chart PowerPoint cannot draw the way Prism does, such as a pie with a negative slice or an area chart with a missing value. Attributed HTML/SVG output is free; clean exports of an unsaved preview need active Prism access. Owners can download saved maker revisions without a current generation plan.
- Current ChatGPT supports broader data, code and editing workflows than image generation alone. For any output, inspect whether it is a generated picture or a chart backed by selected data, then verify the values, labels and editable file you receive. Prism's deterministic makers provide a separate structured rendering workflow.
- Canva Sheets supports CSV/XLSX data, editable linked Magic Charts and bulk brand designs. Some data connector features require Business or Enterprise access. Compare the actual source-update and export workflow rather than assuming a manual-only canvas.

AI chart maker or free chart tool?
The two Gixo routes serve different decisions. Pick the free tool when you need a quick anonymous chart; pick Prism when the chart belongs to a repeatable visual workflow.
- Free Chart Maker: paste data and get a deterministic chart without an account. Use it to inspect the actual rendering before choosing a plan.
- This AI Chart Maker page: use the Prism workspace when you need brand palette control, editable exports, charts alongside diagrams and infographics, and a saved visual workflow.
- Use a spreadsheet or BI tool instead: when you need large datasets, exploratory analysis, live BI dashboards, or statistical modelling. Prism is for clear, presentation-ready visuals where the numbers must stay exact.
Frequently Asked Questions
Does the AI chart maker get the numbers right?
Yes. Prism's chart maker is deterministic — it renders your data with code, not an image model. The value you enter is rendered to SVG exactly, so the number you put in is the number that comes out. There is no AI step that could redraw or garble a digit.
What chart types can I make?
22 chart 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. Choose a compatible representation and review the selected data limits, missing-value notices and display settings.
How much data can one chart hold?
Default limits are up to 20 categories, or 60 for line, area, scatter and combo, with 8 series. Expanded mode permits up to 120 categories and 32 series. Limits vary by representation; review warnings and choose a readable subset rather than assuming that the largest chart is useful.
What formats can I export?
Individual deterministic makers export HTML, SVG, PNG, PDF and PPTX. Compatible charts can contain native editable PowerPoint data; other supported maker visuals use selectable shapes and text. In the PPTX, bar, horizontal bar, stacked bar, line, area, pie, donut, scatter, radar, and bar-and-line combo charts arrive as native PowerPoint charts with their numbers in an embedded workbook that Edit Data opens; waterfall, funnel, Gantt, heatmap, treemap, symbol map, Marimekko, bubble, Sankey, bullet, slope, and dumbbell charts arrive as editable PowerPoint shapes and text, as does any chart PowerPoint cannot draw the way Prism does, such as a pie with a negative slice or an area chart with a missing value. Generated AI infographics, frameworks and decisions use their separate PNG/HTML path. Attributed HTML/SVG maker output is free; owners can download saved maker revisions without a current generation plan.
Can I edit a chart after I make it?
Yes. Change a value, a label, the series, or the chart type and Prism re-renders after the update with the same exactness. Editing is deterministic, so there's the accepted inputs retained; check the updated labels and layout.
Do I need an account?
No. Public makers render and preview without an account, and attributed HTML/SVG output is free. Clean exports of an unsaved preview need an active Prism trial or plan; saved-owner downloads follow a separate rule.
How much does it cost?
From there, Gixo Prism starts at $10/month for Starter (one seat) and rises through Professional, Business and Enterprise; the Brand Kit, which applies your own colours and typeface, starts on the Professional plan. Every maker, AI infographics and the Campaign kit are in the product from Starter; what changes higher up is seats, monthly capacity and the Brand Kit. There's a 14-day free trial with no card up front; card at the gate, not the door.
How is this different from Excel or Canva?
Spreadsheet and design-suite data workflows can also import tables and produce editable charts. Prism focuses on selected maker inputs, display controls and recorded source revisions, with reviewed refresh candidates for recurring work. Compare the source mapping, actual edit and exported file for your reporting task; no tool independently verifies the supplied data.
Can I use it as a graph generator?
Yes. In business use a graph and a chart are the same drawing, so the chart maker is also a graph generator. Paste a table or CSV, pick a bar graph, a line graph, a pie graph or any of the 22 chart types, and the graph is drawn from your values rather than redrawn by an image model. Check the labels, scale and units before you export it.
Explore the Prism visual toolkit
Bring the table, then review the reporting update
For a chart from Excel or several source documents, review the selected table columns and category joins before saving. Missing matches stay as gaps. Chart controls include display precision, axes, annotations and expanded data limits; check their warnings against the source.
Connected data visualization uses public, read-only CSV, JSON, published Google Sheets or Excel links. Profile columns and review filters, sorting or scalar calculations. A refresh stores a candidate to compare and accept; it does not silently replace the current chart or its published copy.
Metric lineage for recurring reporting
Selected Business calculation metrics can be mapped to chart cells with explicit units and a raw or displayed-value convention. The preview retains calculation and cell receipts. For a saved chart, name a reporting period and upload its next calculation pack to store a candidate. Compare it with the accepted data, then accept it as a new revision or cancel it. The current chart and published copy keep their accepted snapshots while the candidate is pending; republishing is separate. The supplied Business inputs still need validation.
For batch chart generation, save an individual maker visual as a reusable template and map CSV columns to its allowed fields. Protected connections, source controls and brand locks stay outside batch input. Review each output before use.
