Figure 29. Adding an activity diagram

The field for creating an activity diagram appears in the program window, the toolbar on the left changes, and the new diagram is displayed on the model navigator.

Example. Let us construct an activity diagram for an additional precedent. Place an order by an actor Buyer (see Fig. 30). Ordering includes specifying your personal contact information, e-mail and payment of the order. Registration starts from the shopping cart when he chooses the option “Checkout”.
