The document discusses Erik Duval's presentation on Edward Tufte's principles of data ink design. It outlines Tufte's key principles: showing the data above all else, maximizing the data-ink ratio by removing non-data ink, erasing redundant data ink, and revising and editing visualizations. The data-ink ratio refers to the proportion of ink devoted to displaying non-redundant data information. The principles aim to clearly display the maximum amount of data with the minimum amount of graphical elements.

- 2. Tufte’s principles • Above all else show the data 2
- 3. • Data ink:“non-erasable core of a graphic...” (Tufte, 1983) • Data-ink ratio = data-ink / total ink = Proportion of a graphic’s ink devoted to the non-redundant display of data- information. = 1.0 – proportion of graphic that can be erased without the loss of information 3
- 4. Tufte’s principles • Maximise the data-ink ratio, within reason • Erase non-data ink, within reason • Erase redundant data-ink • Revise and edit 4
