How to open File Size Viewer with right-click in Dolphin?

[SpectrumDT]

Hello.

I am using Fedora 9 and KDE 4.1. I remember this nice File Size Viewer program (I think that's what it's called) that shows a graphic representation of the contents of a folder and their respective sizes.

In Fedora 8, the File Size Viewer was available when right-clicking a folder in Konqueror (and possibly Nautilus too). It's not available by default in Fedora 9 in Dolphin nor Conqueror. So I want to add it as a right-click option.

First off, I don't know if the program even exists under Fedora 9, but I would think it did.

Second, I don't know the exact name of the program. I've never had to call it from the command line before. Can anyone help?

Thanks in advance.
