import becker.robots.*;

public class GraphMultiple extends Object
{  	 
   public static void main(String[] args)
   {
      GraphCity gc = new GraphCity(7, 1, 1, 10);
      gc.showThingCounts(true);
      GraphBot karel = new GraphBot(gc, 1, 1, Directions.EAST);
      GraphBot hal = new GraphBot(gc, 1, 3, Directions.EAST);
      GraphBot sue = new GraphBot(gc, 1, 5, Directions.EAST);
      CityFrame f = new CityFrame(gc, 12, 9);

      sue.makeGraph();
      hal.makeGraph();
      karel.makeGraph();
   }
