# # Color Scales Using Matplotlib's Colormap 
# 
# Use `scale_color_cmapmpl()`, `scale_fill_cmapmpl()`, or `scale_cmapmpl()` to extract colors from a colormap and apply them to your chart.
# 
# If a colormap is registered with Matplotlib, you can access it by its name. Otherwise, you can pass a cmap object directly.
# 
# **Note:** These functions require Matplotlib to be installed in your environment.
