Revenue by product line — a donut chart rendered by Gixo Prism

A donut chart (also spelled doughnut, and sometimes called a ring chart) shows parts of a whole as arcs around a ring, with a hollow center. Prism renders the ring and its labels; the center is left transparent, so you can drop a headline number over it in your deck or doc. Gixo Prism's donut chart maker is deterministic — no AI image model in the loop. Paste your values or percentages and Prism renders each segment to exact proportion in clean SVG. The number you enter is the number that appears: drawn from accepted values, with display precision set by the chart controls.

What makes a donut chart maker trustworthy?

The arcs have to match your data — not an AI's approximation of it.

Exact segments from your data

Paste your values or percentages and Prism renders each arc to exact proportion — deterministic SVG, drawn from the accepted values; display labels can round according to their settings.

A center left open

The hollow middle isn't just style — use it for the total, a headline percentage, or a short label, so the ring reads at a glance.

Brand-palette governance

Four theme presets — conservative, bold, brand-conservative (default), and brand-bold — plus your own Brand Kit, applied consistently across every segment.

Editable, then clean export

Adjust a value, rename a segment, or switch the theme and the donut re-renders exactly. Export as clean, self-contained HTML/SVG for your deck, doc, or page.

21 other chart types too

Same maker, same exactness: bar in three variants, line, area, pie, scatter, radar, waterfall, funnel, Gantt, combo, heatmap, treemap, and symbol-map charts are one click away when the data calls for a different shape.

Switch to a pie in one click

Donut and pie share the same data — flip between them to see which reads better, without re-entering a single number.

Donut chart vs. pie chart: when to use which

Both show parts of a whole. The difference is the hole — and what you do with it.

Consideration Donut chart Pie chart
Center space Hollow — room for a total, a KPI, or a label Solid — no space for a headline number
Reads best for A few segments where you want a focal total A few segments, simple part-to-whole
Comparing segment sizes Slightly harder — arcs, not full wedges Slightly easier — full wedges from the center
Many small categories Gets cluttered — a bar chart usually reads better Gets cluttered — a bar chart usually reads better

Frequently Asked Questions

What's the best donut chart maker?
Gixo Prism, if the segments have to match your real data. It's deterministic — no AI image model in the loop — so paste your values or percentages and each arc renders to exact proportion, and the center is left transparent for a headline number you add yourself.
What's the difference between a donut chart and a pie chart?
Both show parts of a whole. A donut chart (or doughnut chart) has a hollow center; a pie chart is a solid disk. Review the chosen center and label presentation in the chart controls; a headline annotation is separate from the source proportions. In Prism the two share the same data, so you can switch between them without re-entering anything.
When should I use a donut chart?
Use one when you have a handful of segments and want room in the middle for a focal number you place yourself — a total, a completion percentage, or a category label. For many small categories, or for precise size comparisons, a bar chart usually reads better.
Are the segments exact or estimated?
Exact. Prism's chart maker uses no AI image model — it renders your values or percentages deterministically to SVG, so the number you put in is the proportion that appears, drawn from the accepted values; display labels can round according to their settings.
Is a ring chart the same as a donut chart?
Yes — "ring chart" and "doughnut chart" are just other names for a donut chart: a circular part-to-whole chart with a hollow center. Prism renders all of them from the same donut geometry.
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.
How much does Gixo Prism cost?
There's a 14-day free trial with no credit card. 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.
