Ring Chart
One headline number, with its composition around it. A ring chart - a donut - is a pie with the centre removed. The hole is not decoration: it is where the single number the chart exists to communicate goes.

What is a ring chart?
A ring chart - a donut - is a pie with the centre removed. The hole is not decoration: it is where the single number the chart exists to communicate goes.
Why is a ring chart useful?
It answers 'what is the headline, and roughly what is it made of' in one object, which is why it works as a summary tile above a more precise chart.
How RetainCLM uses it
Put overall retention rate in the centre and the health-band split around it. One glance gives the number and whether it is built on healthy customers or fragile ones.
The chart above is drawn from illustrative demo data chosen to make the visualization legible. It does not describe real RetainCLM customers. On a live account the same chart is drawn from your own customer, usage, billing and support data.
How to read it
Read the centre first; treat the ring as rough proportion only. Angle and arc length are judged much less accurately than bar length.
Limitations to keep in mind
Four slices at most, and never for comparing two rings side by side - people cannot compare angles across separate circles. If you need precision or ranking, use a bar chart.

A ring chart is most useful alongside customer intelligence, customer retention analytics, the full visualization library. RetainCLM builds these views on one unified customer record, so a pattern you notice in one visualization can be followed into the next without exporting anything.
Questions about the ring chart
What is a ring chart?
A donut chart: a circular part-of-whole chart with a hollow centre, which is usually used to display a single summary metric alongside its breakdown.
Is a ring chart better than a pie chart?
Only because of the hole. Removing the centre removes the least readable part of a pie and creates room for the headline number. For accurate comparison of parts, a bar chart beats both.
