Data-ink Ratio

The Data-ink Ratio is a concept in data visualization that measures the proportion of a chart's ink used to represent actual data compared to all ink used in the chart. Higher ratios mean the visualization focuses more on showing the data clearly, with less extraneous decoration or unnecessary elements. Essentially, it encourages creating charts that efficiently convey information without clutter, making it easier for viewers to interpret the data quickly and accurately. A good design maximizes data-ink ratio to improve clarity and effectiveness.
