I have a set of data X,Y,Z representing the coordinates of points that lie on the surface of a sphere. A scatter plot of this dataset on a sphere looks like this generated using ax.scatter.
Scatter plots
I was wondering how I can create a 3D density plot of this that is a colour map where the region where there are more points is a different colour compared to where there are fewer points. I tried Mayavi but it is not supported by my environment.
