Distribution plot of the response variable will indicate where the data lies. A common example can be distributuon of users as a function of age. This will indicate from which age group the maximum users lie in.
However, one may encounter a bimodal distribution in reality during the exploratory analysis. That means there might be more than one peak, of course the other peaks may not be as prominent as the major peak. This indicates, that the user age group is in clusters and not around a specific value.
