Description: The marker edge color in a plot is a visual property that defines the color of the outline surrounding each marker in a graphical representation. In data visualization libraries, this feature allows users to customize the appearance of data points, enhancing the clarity and aesthetics of the plot. The edge color can differ from the marker color itself, providing additional contrast and helping to highlight data in situations where the background or marker color might hinder visibility. This property is especially useful in plots with multiple data series, where visual differentiation is crucial for the correct interpretation of information. Furthermore, the use of edge colors can be an effective tool for conveying additional information, such as the importance or status of certain data points. In summary, the marker edge color is a key element in graph customization, allowing users to create more effective and visually appealing visualizations.
