    This case-sensitive 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. |
