When presenting data, especially to a non-technical audience, clarity is paramount. The \<strong\>Data-Ink Ratio\</strong\>, a concept introduced by visualization expert Edward Tufte, provides a powerful framework for achieving this clarity. It's defined as the proportion of a graphic's ink (or pixels) used to display essential, non-redundant data information. The goal is to maximize this ratio by removing what Tufte calls "chart junk"—visual elements that don't add new information and only serve to distract or clutter the visualization.
