+      GrandPerspective is a small utility application for macOS that graphically shows the disk usage within a file
+      system. It can help you to manage your disk, as you can easily spot which files and folders take up the most
+      space. It uses a so called tree map for visualisation. Each file is shown as a rectangle with an area proportional to
+      the file's size. Files in the same folder appear together, but their placement is otherwise arbitrary.
