The following examples include "steps" attribute shown as shading inside the radial arc, "delta" which is the

difference of the value and goal (reference - value), and "threshold" to determine boundaries that visually alert you if the value cross a defined threshold.

A radial gauge chart has a circular arc, which displays a single value to estimate progress toward a goal.

The bar shows the target value, and the shading represents the progress toward that goal. Gauge charts, known as

speedometer charts as well. This chart type is usually used to illustrate key business indicators.

The example below displays a basic gauge chart with default attributes. For more information about different added attributes check [indicator](https://plot.ly/javascript/indicator/) tutorial.

Gauge charts are useful for comparing values between a small number of variables by using multiple gauges.
