Answer:
A visual tool that works hand in hand with the agent's dialogue is the **User Interface (UI)** or **Graphical User Interface (GUI)**. The UI or GUI includes visual elements such as screens, windows, buttons, icons, and other graphical elements that facilitate interaction between the user and the agent. It provides a way for users to input commands and receive feedback or information in a visual format. The UI complements the agent's dialogue by presenting information in a more intuitive and interactive manner.
