Hi - interesting point about the Whales not being able to touch your holdings, I guess not... I actually just calculated that I make something like an 8% return just by auto-voting a select few people, really passive income that (and my next very simple blog post).

As to Google Sheets - yes - it's just the basic stuff I use... very easy, just 'insert chart' and you can download as a jpeg then just drag into your posts. You can even create Tree Maps, which I'm a big fan of. If you really want to kick it with vizuals, you want Tableau (Tableau Public is free), although for ease of use Google Sheets is great.
