Make your data visualizations and dashboards more engaging with Radial Gauges that show off KPIs with rich style and interactivity. The round and semi-round gauges are powerful, easy to use, and highly configurable to present dashboards capable of displaying clocks, industrial panels, automotive dashboards, and even aircraft cockpits.

The following code snippet demonstrates how to initialize the igRadialGauge.
