                              float scalePos)
Constructor.

Parameters:
graph - Graph representation, contains the positions of the vertices.
out - Output stream writer.
minVert - Diameter of the smallest vertex.
fontSize - Font size of vertex annotations.
backColor - Background color.
blackCircle - If true, draw black circle around each vertex.
showEdges - If true, draw the edges between the vertices (if possible).
scalePos - Scaling factor for the layout to adjust to drawing area.
