The pie.padAngle() function in D3.js is used to set the padding angle between consecutive arcs. When an angle is specified, it sets the pad angle to the given angle or function and returns a pie generator. When the angle is not specified, it returns the current pad angle accessor, which defaults to no padding.
Syntax:
pie.padAngle( angle )
Parameters: This function accepts a single parameter as mentioned above and described below:
- angle: It is a number or function that specifies the pad angle in radians. It is an optional parameter.
Return Values: This function does not return anything.
Below given are a few examples of pie.padAngle() function in D3.js;
