What is the method for creating a path with curves at the corners?

edit

The method for creating a path with curves at the corners is to use the Pen tool in a vector graphics software such as Adobe Illustrator or Inkscape. First, draw a straight path using the Pen tool. Then, click and drag a handle from the corner anchor point to create a curve. Repeat this for each corner until the path has the desired curve. Adjust the curves as needed by dragging the handles or using the anchor point tool.
