This code defines a drawing application that allows users to draw various shapes and lines on a picture box. It imports drawing-related namespaces and defines a pen and graphics object. Buttons trigger handlers to draw lines, ellipses, rectangles, arcs, pies, polygons, beziers, and clear the picture box using the graphics object.
