https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      fsv (pronounced eff-ess-vee) is a file system visualizer in cyberspace.
+      It lays out files and directories in three dimensions, geometrically
+      representing the file system hierarchy to allow visual overview
+      and analysis. fsv can visualize a modest home directory, a workstation's
+      hard drive, or any arbitrarily large collection of files, limited only
