The `title()` function in Matplotlib is used to set the title of a plot. This title serves as a key component in conveying the primary message or theme of the visualization, helping viewers quickly grasp the purpose of the data being presented. By providing a clear and informative title, users enhance the interpretability and professionalism of their static visualizations.
