# Difference between scatter-plot and a dotplot

This question is now haunting me like anything, I am unable to understand , what is the difference between scatterplot and a dotplot? Is there any difference at all? or often people use them interchangeably. I have asked this question to several people , some say its same but some other say its different but no one able to explain any difference ? Sorry if this is a newbie question, but some one can explain this to me , I think that would be great help.

Thanks
