You need to turn generating the polygon off...

package require vtk
package require vtkinteraction

vtkRegularPolygonSource circle
   circle GeneratePolygonOff
   circle SetNumberOfSides 360

vtkPolyDataMapper mapper
   mapper SetInputConnection [circle GetOutputPort]

vtkActor actor
   actor SetMapper mapper

vtkRenderer ren
   ren AddActor actor

vtkRenderWindow renwin
   renwin AddRenderer ren

vtkRenderWindowInteractor iren
   iren SetRenderWindow renwin
   iren AddObserver UserEvent {wm deiconify .vtkInteract}
   iren Initialize
