How to plot a 3-D "hotspot" figure

I have a set of coordinates (x,y,z) for which there is a value f(x,y,z) I would like to illustrate. For the most part f will be close to zero, but in the vicinity of a small number of coordinates f will take an arbitrarily large value. My ambition is to illustrate this in such a way as these coordinates of interest appear as 'hotspots' within a cuboid defined by designated bounds on x,y,z. Should this be possible I aniticipate that the illustration would appear as a small number of spheres within the cuboid. Can anyone advise how such a plot can be implemented?

I would suggest looking at this example for the scatter3 function: scatter3 with varying marker colors
You could use your f(x, y, z) as the c (color) argument. It is also possible to have varying marker sizes.

A more refined version, much as I was aiming for. A good illustration of the contribution of @Les Beckham
