Turn category shares into a donut chart with a clear center.
Give Vizify your categories and values plus the metric worth centering. It plans slice count, label style, and a legend so the share-of-whole story stays legible.
Open center reserved for a total, metric, or label Readable at up to six or seven slices before grouping "Other" Percentages, raw values, or both on each slice

What it does
Built to hand back finished work.
A center that earns its space
Vizify treats the ring's open middle as real layout, not empty space — plan a total, headline metric, or short label instead of leaving it blank.
Slice count kept legible
Past six or seven categories, thin slices stop being readable. Vizify groups minor categories into "Other" when you ask, instead of cramming every value onto the ring.
Labels that match how you'll present it
Choose percentages, raw values, or both, and Vizify keeps the label style consistent across every slice and the legend.
Continue with the context intact

FAQ
Questions, answered.
What's the difference between a donut chart and a pie chart?
Both show category shares of a whole, but a donut chart's open center can hold a total or headline metric, while a pie chart uses the full circle for the slices themselves. If you don't need the center space, [Pie Chart Maker](/tools/pie-chart-maker/) is the more direct choice — Vizify treats them as two separate chart formats rather than one with a hole cut out.
What should I put in the center of the donut?
A single number or short label works best — the total, a key percentage, or the category leading the mix. Say what you want centered in your brief; without one, Vizify leaves it as a simple total.
How many categories can a donut chart show clearly?
Up to about six or seven slices stay easy to compare by eye. Beyond that, ask Vizify to group smaller categories into an "Other" slice so the ring doesn't turn into a ring of slivers.
Can I show both percentages and raw values on the slices?
Yes. Set Labels to Both, or leave it on Percentages or Values alone if you want a cleaner ring with fewer numbers competing for space.
Does the donut chart work for values that don't add up to 100%?
A donut chart represents parts of one whole, so values should sum to the total you're depicting. If your numbers don't sum cleanly, say whether that's expected (such as multi-select survey answers) so Vizify doesn't force them into a misleading ring.
What if two categories are close to the same size?
Mention it in your brief. Vizify can order slices and choose contrasting colors so two similarly sized shares stay visually distinguishable instead of blending together.
Is the donut chart format guaranteed to always be available?
Donut charts use Vizify's extended chart library rather than a core diagram type, so treat it as the current supported format rather than a permanent guarantee. If it's ever unavailable, Vizify will say so instead of silently rendering a different chart.
Should I use a donut chart instead of a bar chart for comparing categories?
Use a donut chart when the point is each category's share of one whole. If the point is comparing raw values across categories rather than their proportion of a total, [Bar Chart Maker](/tools/bar-chart-maker/) usually reads more precisely, especially with several categories.
Can I request a specific color for one slice, like a brand color?
Yes. Name the category and the color you want in your brief, and Vizify applies it while keeping the remaining slices distinguishable.
Do I need an account to start?
No. You can prepare the brief and choices here without one. Sign in to Vizify when you're ready to generate, save, or reuse the chart.
Can I revise the chart after the first version?
Yes. The brief you build here is a starting point. In Vizify you can edit the values, switch labels or style, and regenerate before saving the final version.
Data that produces a readable ring
List each category with its value and make sure the set represents one coherent whole — market share of the same market, budget lines from the same budget. If categories don’t sum to a meaningful total, say so in your brief instead of letting Vizify assume they should.
Putting the center to work
The open middle is what separates a donut chart from a pie chart, so decide what belongs there before you generate: a grand total, a single headline percentage, or a short label naming the leading category. Leaving it blank wastes the chart’s most distinctive feature.
Donut, pie, or something else
Choose a donut chart when the center metric matters and you have roughly two to seven categories. If you don’t need center space, Pie Chart Maker is simpler. If the comparison is about raw values rather than share of a whole, Bar Chart Maker usually communicates it more precisely.
