How can Gestalt principles improve your data visualization?

The Gestalt principles are theories developed by German psychologists in the 1920s, explaining how humans naturally organise visual elements into groups or unified wholes when perceiving objects. These principles include Similarity, Proximity, Closure, Continuity, Figure/Ground, and Symmetry, guiding our understanding of how elements are related and how we prioritise them visually. In data visualisation, applying Gestalt principles can significantly enhance clarity and comprehension. For instance, Similarity helps identify patterns and categorise data by suggesting that comparable things are viewed as more connected. Proximity implies the perception of nearby elements like a group helps organise information rationally.

The Gestalt principles are a set of principles that describe how humans perceive and organize visual information from the field of Psychology. Here are the main Gestalt principles: Proximity: Objects that are close to each other are perceived as related. Similarity: Similar objects in size, shape, color, or texture are perceived as related. Closure: Humans perceive incomplete or fragmented visual elements as complete shapes or patterns. Symmetry and Order: Humans perceive symmetrical and orderly arrangements as more aesthetically pleasing and easier to process. By incorporating these Gestalt principles into data visualizations, designers can create more engaging and effective visual representations of complex datasets. #DataViz

Think of Gestalt principles as the secret sauce for creating visually stunning and impactful data visualizations. Picture this: you’re designing a dashboard to showcase quarterly sales performance. By skillfully applying principles like proximity and similarity, you transform a mundane spreadsheet into an eye-catching masterpiece. Imagine colorful clusters of data points grouped by region, effortlessly guiding viewers to spot trends and outliers with just a glance. It’s like turning data into a captivating story that practically leaps off the screen, leaving your audience eager for more insights. That’s the power of Gestalt-inspired design in data visualization!

In a dashboard containing separate elements, grouping similar sections together will encourage end users to look at them together. This can be achieved by reducing the white space between them (proximity) or by using a subtle border or shared background (closure). Note that similar sections does not necessarily mean similar chart types, but sections that answer the same - or a related - question.

Drawing comparable data points or items together creates visual clusters the viewer's brain naturally links with the same category, decreasing the cognitive burden and simplifying data processing and interpretation. In practice, proximity can demarcate different sections or categories within a single chart, emphasise relationships between variables, or segregate distinct datasets within a larger visualisation. For instance, in a complex dashboard, keeping related metrics and graphs near each other helps users quickly make connections and draw insights. Moreover, applying proximity can guide the viewer's attention to important data points or trends, fostering a more intuitive navigation through the data.

Using colours meaningfully and consistently will make your visualisations far easier to understand. Break this principle and you risk confusing your audience. A word of warning, though: the more colours you use, the harder it is for the brain to associate them with a category. Here is may be preferable to allow the user to select a category one by one, and show unselected categories in a neutral colour (e.g. grey).

Data is dynamic. Therefore, Gestalt concepts may adapt to different situations when used in data visualisation. For instance, animation can display real-time data. Animations use continuity and closure to show data changes over time, helping viewers understand trends and patterns. Interactive components improve data visualisations. Hover effects and clickable elements can add detail to data, letting users explore it based on their interests. User emphasis on specific data points while keeping an overall perspective is achieved through figure/ground interplay. Finally, visualisations affect emotions. Gestalt concepts apply emotionally and technically since colour, shape, and arrangement can elicit emotions or urgency.
