Pigshell – Unix the Web
Author here.- Please use a desktop browser (Chrome preferred). While mobile browsers kinda-sorta work if you're just clicking through the examples, keyboard input doesn't work on mobiles (yet).- Pigshell has few users (in fact, using the plural is a  slight marketing exaggeration) so please bear with me for any teething issues, broken links, inadequate documentation...- One of the practical use cases is copying files across Google accounts, and backing it up to your desktop. (Details here: http://pigshell.com/v/0.6.2/doc/gdrive.html) The nice thing about a unix approach is that the exact same cp command can be used to copy GDrive to Dropbox, or any other supported filesystem.- Some more D3 visualization examples here, using Mike Bostock's gist viewer: http://bl.ocks.org/ganeshv (Do use the "Open in a new window" links, like this one: http://bl.ocks.org/ganeshv/raw/46cc526d41d16995ccdc/).
