Description: The text margin in data visualization libraries, such as Matplotlib, refers to the space surrounding the text in a plot, allowing for better readability and visual presentation. This margin is crucial to prevent text from overlapping with other elements of the plot, such as axes, legends, or data points. In these libraries, margins can be adjusted to optimize the layout of text and enhance the clarity of the information presented. Margins can be defined in different directions: top, bottom, left, and right, allowing for precise control over the text’s placement in relation to other components of the plot. An appropriate margin not only improves the aesthetics of the plot but also facilitates the understanding of the message being conveyed. In summary, the text margin is a fundamental aspect of creating effective and visually appealing plots in data visualization.
