This page is a tutorial on SVG path element's elliptical arc command
[see SVG Path Tutorial]
A rx ry rotate large_arc_flag sweep_flag x y→ Draw a elliptical arc from the current point to x,y. The ellipse has radius rx ry (major/minor axis), rotated by rotate (in degrees, clockwise.). The large_arc_flag and sweep_flag should be 1 or 0, they control which section of the ellipse to use.

Large Arc Flag and Sweep Flag
When a line cuts ellipse into 2 arcs, there's a larger arc and a smaller arc. The parameter large_arc_flag specifies which arc to use.
The sweep_flag specifies which side of the path the curve is drawn.
