If you have "value" as a function of latitude and radius, isn't that a 2D (not 3D) scalar field? Which can be plotted using a regular heatmap.
If you want a curved edge where depth=0 (radius=?), that's not too difficult to achieve. Not quite sure what continent boundaries mean in this context, but that could possibly be added to. Or do you want a 2D slice superimposed within a 3D space? And if so, does it need to be dynamic? (i.e. Rotate the whole thing, with a trackball/mouse). Note that the further you go down the list above, the more work is required.
