The d3.path.quadraticCurveTo() function is used to draw the quadratic bezier segment to a certain point from the current points via certain control points.
Syntax:
path.quadraticCurveTo(cpx, cpy, x, y)
Parameters: It takes four parameters as given above and described below.
- cpx: It is the x-coordinate of the quadratic control point.
- cpy: It is the y-coordinate of the quadratic control point.
- x: It is the x-coordinate of the ending point.
- y: It is the y-coordinate of the ending point.
