This screenshot shows part of the content of the Skill Tester after a user has entered "What is the number of calories in a pizza".
On the left side of the screen is the conversation, including the user's input and the skill's response.
On the right side of the screen is a pane showing a visual representation of the flows and individual states traversed in the conversation. In this case, it shows a progression from the Main Flow to the handler.startSkill flow (within which it traverses the checkUserType and welcomeUser states) to the Main Flow (again) and then (again) to the handler.startSkill flow (within which it traverses the checkUserType, welcomeUser, and endFlowAndKeepTurn states) states. Then it goes to the Main Flow (for a third time) and then to the pizza.ans.genericHandler flow.
