What is a fundraising donut chart?
A donut chart (also called a ring chart) is a circular visualization where a ring fills progressively to show percentage completion. For fundraising, the ring fills as donations come in — 25% filled means 25% of the goal reached. It's a modern, compact alternative to a thermometer that reads well at any size.
How does a donut chart compare to a thermometer?
Both show progress toward a goal, but thermometers are vertical and donut charts are circular. Thermometers are the traditional choice for fundraising campaigns; donut charts feel more contemporary and suit pages where a square or circular format fits better — sidebars, mobile-first layouts, and report pages. For classic "fundraising thermometer" recognition, thermometer styles are more familiar to donors.
When will the donut chart style be available?
The dedicated ring/donut chart style is on the roadmap. In the meantime, the Gauge (style 16) and Chrome Dial (style 17) are circular formats available today for Pro users. Let us know if the donut chart is a priority and we'll factor that into scheduling.
Can I embed a donut chart in an email?
Yes — all thermometerchart.net charts embed as plain
<img> tags, which work in HTML emails wherever image display is enabled. This is true of the gauge charts available today and will be equally true of the donut chart when it launches.Start with a circular gauge chart today
