"Under Formulating Your Brief, Kirk (2019) presented the list of roles or “hats” of data visualization design. In 2012, the author presented the same topic but with a total of 8 “hats”. After reading the information from 2012 (his discussion and the slide presentation he includes), compare the information discussed in our text. Please provide your perspective why there is a change from 2012 to 2019. This perspective would be your own opinion. This would not be research discovered about the differences from another source. Please include the following:
- What are the similarities and the differences in these two lists of roles?
- Why do you think the list has been refined to the list presented in 2019?
- What is your suggestion for the next revision and why?"
