In the past, I've done it one of two ways but you need some data processing software (such as FME or GIS or Spatial database) to make it work. Method 1: Process the data and come up with a single point that has a count of the number of items at the same point (Point on Point) and create a resultant table to store the values. Label the point with the number of points on top of each other. Method 2: Offset the points by a distance (x,y) that could rotate around the compass (or other method depending on the number of points that may overlap) then draw a line from the new point to the original point to show the user the source.
Perhaps you could try buffering the points based on a increasing buffer value and then order the items so that the largest buffer displays first etc... Without the third dimension you are going to have to be a little bit flexible and creative in your solution...
