While a lot of us tinker with responsive design, I thought this simple albeit traditional data visualization is a good balance of good design with a nice adjustable toolbox. I think my favorite part of this graph is the color palette – simple, balanced, and intuitive, as each the strength of the blue shades indicate the increases whereas the grey represents the status quo.
And you know, we should all save more. People under thirty-five in the US have a negative savings rate, so put that plastic back in your pocket. (David, you keep doing you – your generation seems to be doing okay.)
