Blog post on scikit-image by Eric Chiang

[Viral Parikh]

Hi All,

Has anyone run the below part of the code mentioned in the blog - 

ggplot(pd.DataFrame(),aes(fill=True,alpha=0.5)) + \
    geom_density(aes(x=gray_image.flatten()),color='green') + \
    geom_density(aes(x=equalized_image.flatten()),color='orange') + \
    ggtitle("Histogram Equalization Process\n(From Green to Orange)") + \
    xlab("pixel intensity") + \
    ylab("density")

I run and I keep getting errors. Can anyone tell me what - pd.DataFrame() mean 
over here?

Thank you in advance!


Best,
Viral
