Dial Chart

A Dial chart is a visual representation that displays a single value within a specified range or scale. It resembles a speedometer or a Dial you might find on a dashboard. The position of a needle or a pointer on the Dial indicates where the value falls within the given range. Dial charts are often used to quickly convey whether a particular value is within acceptable limits or to show progress towards a goal. They provide a straightforward way to visualize data points in comparison to a predefined range or target.
