Question 8True or False. The backend layers three built-in interface classes are FigureCanvas, Renderer, and Event.1 pointTrue False

True or False Analysis

To determine whether the statement regarding the backend layers' built-in interface classes—FigureCanvas, Renderer, and Event—is true or false, we need to consider the context of visualization libraries, particularly in Python's Matplotlib.

1. FigureCanvas: This class is indeed a part of Matplotlib's backend and is responsible for rendering the figure onto a canvas.
2. Renderer: This class is also a fundamental part of Matplotlib's backend, responsible for drawing the figures and handling the painting into the canvas.
3. Event: This refers to event handling in Matplotlib, which captures user interactions like clicks or keyboard inputs.

Conclusion

All three classes mentioned—FigureCanvas, Renderer, and Event—are integral parts of the backend layers in Matplotlib.

Final Answer

True. The statement is correct. The backend layers include the built-in interface classes FigureCanvas, Renderer, and Event.
