A data analyst is designing a dashboard for regional sales managers. The dashboard must prominently display the current month's sales target achievement for each region, showing both the actual sales and the target, with a clear visual indicator if the target has been met or exceeded. Space on the dashboard is limited. Which visualization design principle should the analyst prioritize to meet these requirements?
- AData Ink Ratio
- BProgressive Disclosure
- CInteractivity
- DData Storytelling
Show answer & explanationAnswer & explanation
Correct answer: A. Data Ink Ratio
The Data Ink Ratio principle emphasizes maximizing the data-ink and minimizing the non-data-ink. Given limited space and the need for clear, prominent display of key metrics and their status, reducing unnecessary visual elements will ensure the data stands out and is easily understood.
Why the other options are wrong
- B. Progressive disclosure hides complex information until needed, which isn't the primary concern when displaying core metrics prominently.
- C. Interactivity allows users to explore data, but the initial display of key metrics against targets is a static design challenge for space efficiency.
- D. Data storytelling is about narrative flow, not primarily about efficient use of space for metric display.
Data Ink Ratio
A design principle by Edward Tufte stating that the proportion of a graphic's ink devoted to the non-redundant display of data-information should be maximized.
- Maximize 'data-ink': ink used to display data.
- Minimize 'non-data-ink': ink used for labels, borders, frames, etc.
- Aims for clarity and efficiency in data visualization.
