Description: Tick label rotation in Matplotlib refers to the angle at which the axis labels are displayed on a plot. This adjustment is crucial for enhancing the readability of labels, especially when they are long or when there are many labels in a limited space. By rotating the labels, overlap can be avoided, making it easier to interpret the represented data. The rotation can be adjusted in degrees, allowing the user to choose the angle that best suits their needs. This feature is part of the flexibility offered by Matplotlib, one of the most popular libraries for data visualization in Python. Label rotation not only improves the aesthetics of the plot but also contributes to better visual communication of information, enabling viewers to quickly understand the presented data. In summary, tick label rotation is an essential tool in creating clear and effective plots in data visualization.
