    “Beef-up” flowcharts for Web/Flash developers..Especially if complex processes, like e-commerce,applets, or utilities (calculators, games, specializedservices, etc.)
  2. Basic flowcharting shapes
    The terminator symbol (an ellipse orrounded rectangle) marks the startingor ending point of the process flow.Contains the word "Start" or "End."
