Edward Tufte's Course on Data Viz

Just took Edward Tufte's one-day course on data visualization.  These nuggets of wisdom stuck out to me from his lecture:

  • A common problem with data visualization is smoothing out the data - hiding the numbers.
  • No matter how beautiful your interface is, it would be nicer if there were less of it - the data is the interface.
  • Design can't salvage failed content. 
  • Don't design for the organizational hierarchy behind the data; design for what people actually come to your site for.
  • Dimensional compression is the fundamental problem.  Go out in the world and see how your data is collected.
  • Your contempt for the audience leaks through...you shouldn't dumb the data down.  

Excited to delve into his books next!
