Andy Kriebel together with Andy Cotgreave initiated a MakeoverMonday series to challenge their-selves and others to redesign a dataviz (you can find the project here: http://vizwiz.blogspot.nl/p/makeover-monday-challenges.html). They provide the original dataviz and the source (small) data. I'm participating with my own approach in Illustrator, trying to trigger myself into new/other graphical styles and/or forms. I'll try to include my sketches as well.
The data itself is mostly a small part of a bigger story and I didn't check up on all the background-info, sometimes even the statistics are questionable. Do consider these visualizations purely as an exercise and please do not communicate/share them as facts!
