Problem

Matplotlib's default color cycle of 10 colors is insufficient for effectively visualizing plots with more than 10 elements. The repetition of colors makes it difficult to differentiate and understand the data associated with individual elements. This presents a major challenge for data analysis and visualization, especially when dealing with large datasets.

Proposed solution

1. Extend the default color cycle: This could involve adding more pre-defined color options to the existing palette.
2. Utilize colormaps: Employing colormaps effectively can provide a wider range of distinct colors for visualizing many elements.
