Petroff style sheets#
This example demonstrates the "petroffN" styles, which implement the 6-, 8- and10-color sequences developed by Matthew A. Petroff[1] for accessible datavisualization. The styles balance aesthetics with accessibility considerations,making them suitable for various types of plots while ensuring readability anddistinction between data series.
