graphs could be a little bit nicer, but the data are great! Could you post a list to raw data (in *.csv file)? You can host it on sites like http://gist.github.com/
BTW, I am going to use that data in my project "B.O.O.S.T":
Project "B.O.O.S.T. - Big Organized Outing To Steem ", aka How to bring 10k new users to Steem
Brace yourself, Wednesday is coming :)
I am working on it - i normaly use custom tool for this with dynamic animations etc. I will try to set up a site for it within this week
