Private Sub MainFormLoad(sender As System.Object, e As System.EventArgs)
		
		'Defines new bitmap
   		Dim states As bitmap= new Bitmap(mapdraw.Width,mapdraw.Height)
   		
		'Draws image to Picturebox
		Me.mapdraw.Image=states
   		
   		'Defines your graphics holder
   		Dim g As Graphics = Graphics.FromImage(states)
		Dim greenb as solidbrush=new solidbrush(color.green)
		'creates polygons in the shape of states
		Dim WASHINGTON() As Point = { _
		New Point(95,35), _
