This code system http://hl7.org/fhir/imagingselection-2dgraphictype defines the following codes:

Code | Display | Definition
point | POINT | A single location denoted by a single (x,y) pair.
polyline | POLYLINE | A series of connected line segments with ordered vertices denoted by (x,y) triplets; the points need not be coplanar.
interpolated | INTERPOLATED | An n-tuple list of (x,y) pair end points between which some form of implementation dependent curved lines are to be drawn. The rendered line shall pass through all the specified points.
circle | CIRCLE | Two points shall be present; the first point is to be interpreted as the center and the second point as a point on the circumference of a circle, some form of implementation dependent representation of which is to be drawn.
ellipse | ELLIPSE | An ellipse defined by four (x,y) pairs, the first two pairs specifying the endpoints of the major axis and the second two pairs specifying the endpoints of the minor axis.
