For my bad infographics example, let's take a look at this one pictured above. This graphic is telling me information I want to know but not in an easily understandable way nor is it nice to look at. There seems to be a lot of extraneous decoration and attempts at clarification that make the graphic needlessly complicated. The blue and red bars should suffice, we don't need the 'D' and 'R' labels. The typefaces used are more distracting than helpful. The unnecessary colors on the axis labels are similarly distracting. What do you think?
Conversely, I find this infographic from Wired magazine to be very useful. Everything on the page seemingly has a purpose, from the colors to the text to the graphic elements.
