Create an HTML5 canvas element on which you want to draw the circle.

Draw a circle from a given percentage value (90%).

    //set type of value which the circle will present
    valueType : PERC,
    //set max value
    maxValue : 100
},90).startDrawing();

Draw a number counter that fills the arc after init.

new Circle(document.querySelector("#example"),{
    valueType : NUMB,
    maxAngle : (240) ,

},9090).startDrawing();

    valueType:TIME,
    maxValue : STimeToTimeStamp("00:05:10"),
    withValue:true,
    withAnimation : true,
    animationDuration : STimeToTimeStamp("00:01:05")*1000
