Why there is no exact picture of softmax activation function? I was wondering why there is no precise picture of the softmax activation function on the internet. Is it difficult for the plot or what is the reason behind that since I want to compare it with a sigmoid function?
I just found the following funny pictures from dataaspirant which is not available anymore:

Can anyone illustrate a Softmax function graph? and explain why one is faster than another one due to the above picture?
Softmax is a multivariable function, generally. You wouldn't take a softmax of a single variable just like you wouldn't take a maximum of a single variable. It's difficult to plot functions of more than 2 variables because our eyes see in 3 dimensions.

A sigmoid is a 1 dimensional function. In your picture, they are applying a sigmoid to every variable separately.
