Description: Label rotation is the angle at which labels are displayed on a graph, especially on coordinate axes. This parameter is crucial for improving the readability of graphs, as labels can overlap or be difficult to read if presented at a standard horizontal angle. By adjusting the rotation of labels, users can optimize data presentation, making visual interpretation easier. In various data visualization tools and libraries, label rotation can be easily customized, allowing users to choose from different angles, such as 45, 90, or even custom angles. This flexibility is particularly useful in graphs with many categories or in those where labels are long. Label rotation not only enhances the aesthetics of the graph but also contributes to better communication of information, making data more accessible and understandable for the viewer. In summary, label rotation is an essential tool in data visualization that helps present information clearly and effectively.
