Also, just cool. What visualization has stuck with you your whole life?
"All 1,943 Cornell Faculty were asked to respond to the following question:
Of the many charts (graph, map, diagram, table and 'other') you have seen in your life, which has been the most important, remarkable, meaningful or valuable?
On the archival paper provided, they were asked to create a copy of the chart and in the remaining space annotate notable attribute of the data and the image, describe what they remembered about first seeing this image and comment on why they chose this image.
All other Cornell community members are invited to share their favorite chart by visiting the display table in Mann Library near the reference desk on the first floor."
Ok, while you might not be able to get away with this at some schools, this is an amazing hook to let (older) kids explore the power of taking piles of data and transferring it to an infographic.
