plt.scatter(X[ : ,0], X[ : ,1]) here why did we plot columns of X on different axes?

Hi, if your X has two features lets say X denotes dog name and lets say bruno the labra dog(a point in some space) has 2 features-(height and weight). Now for seeing where the point lies in the space we are plotting X[:,0] AND X[:,1]. Its just like plotting x and y for a line’s equation where a line has two variable features x and y for the equation y-mx+c=0. So just like that x[:,0]=x and x[:,1]=y. SO we are plotting these.
