1. Visualisation do we spend too much time exhibiting our work?
Goals in data visualisation X1, Y1, x2, y2 … data Encoding Decoding Exhibit “Wow, X & Y looks amazing, I need to find out more!” Explore “I wonder how x relates to y” Explain “X does y”
Goals in data visualisation X1, Y1, x2, y2 … data Encoding Decoding Exhibit “Wow, X & Y looks amazing, I need to find out more!” Explore “I wonder how x relates to y” Explain “X does y”

Lets try ‘modelvisualisation’… X1, Y1, x2, y2 … data Encoding Decoding Exhibit “Wow, X & Y looks amazing, I need to find out more!” Explore “I wonder how x relates to y” Explain “X does y” Explain (2) “… because of A & B, X does y” ?
2. Interpretation do we recognise why we disagree?
