The Ring Summary is a another form of the Summary chart. Just as the name implies, the Ring Summary displays the value and other elements, such as smiley, emoji, prefix or suffix, within a colored ring. See the Summary chart page for more information.
Ring Summary charts are suitable for displaying smaller numerical values in a more prominent way.
You can apply conditional formatting to determine the color of the ring, for example, red or yellow until a target is met or exceeded, at which point it will turn green.
Prepare the data in the grid, click the Chart 
button, then click the KPI chart category button and select the Ring Summary option.
