Final answer:
Processing is known for its graphics library, the draw() function is continuously called to update visuals, the keyword 'void' does not indicate that a function does not produce anything visual, and event handlers implement interactivity.
Step-by-step explanation:
False. Processing is known for its graphics library, which makes it a popular choice for artists. The draw() function is not called every time a user hits a key; it is called continuously to update the visuals on the screen. The keyword 'void' actually indicates that a function does not return anything, not necessarily that it does not produce anything visual. Event handlers do implement the interactivity feature of a Processing program, allowing it to respond to user actions such as mouse clicks or keyboard inputs.
