This is an illustration of the Skill tester. It's divided into two areas: on the left is the Testing Skill chat window and on the right is a pane with three tabs called Conversation, Routing and JSON. In this image, there's chat messages in the Testing Skill chat window and Conversation is selected. The Conversation pane shows states, a vertical metro-stop like representation of states in the dialog flow, a table that describes the postback actions using Label, Action, and Variables columns, and a window called Variables.
