Frequently asked questions
What is the centre of the donut for?
The hole is a natural place for a headline figure, so the tool prints the total of all your slices there along with a caption you can change. That turns the chart into a KPI card that shows both the overall number and its breakdown at a glance.
Can I change how thick the ring is?
Yes. The hole size control moves the inner radius between a thin ring and a very wide hole. Thinner rings suit dashboards with a large centre figure, while thicker rings read more like a classic pie when you have many slices.
Does it handle a single category or a zero total?
Yes. A single value draws as a complete ring rather than a broken arc, and if every value is zero or blank the tool shows a short explanation of what to fix instead of rendering an empty or broken shape.
