+## Description
+
+How to add a centered label to the RadialGauge component?
+
+## Solution
+
+To add and center a label on the RadialGauge, wrap the RadialGauge inside a `div` element and use a `span` element for the label. Afterward, apply CSS styles to these elements for appropriate positioning.
