Disk

Disk[{x, y}, r]
is a two-dimensional graphics primitive that represents a filled disk of radius r centered at the point x, y.

Disk[{x, y}]
gives a disk of radius 1.

Disk[{x, y}, r, {

₁,

₂}]
gives a segment of a disk.

Disk[{x, y}, {r_x, r_y}]
gives an elliptical disk with semi-axes of lengths r_x and r_y, oriented parallel to the coordinate axes.

Disk[{x, y}, {r_x, r_y}, {₁, ₂}] yields an elliptical disk segment obtained by transforming a circular disk segment with the specified starting and ending angles. »

Scaled[{dr_x, dr_y}] or Scaled[{dr_x, dr_y}, {r_x, r_y}] can be used in the radius specification. The dr_i are in scaled coordinates, and the r_i are in ordinary coordinates.

FaceForm and EdgeForm can be used to specify how the interiors and boundaries of disks should be rendered. The default is that no explicit edge is drawn. »
