Size makes the larger squares appear more important than the surrounding shapes. In the example below, similarity in size causes the larger shapes to stand out and form a group, even though all the shapes are the same. Size is another useful tool we can use in creating similarity. No other attribute can beat color when it comes to assigning relationships. In the example below, notice how the colored shapes have a strong effect in assigning a grouping or relation, even when different shapes are included. Similarity is particularly affected by color. Similarity helps us organize objects by their relatedness to other objects within a group and can be affected by the attributes of color, size, shape and orientation. The gestalt principle of similarity says that elements that are similar are perceived to be more related than elements that are dissimilar. Understanding how these principles work, and how to use them in your designs, produces stronger and more engaging work.Īre you ready to improve your designs? Let’s begin by digging into similarity. As a visual designer, and now an interaction designer, I apply these principles on a regular basis to create relationships and differences between elements in my designs. The gestalt principles - similarity, proximity, closure, figure-ground, continuance and common fate - are a popular tool used by designers for visually organizing information. The gestalt grouping principles of visual perception describe this organization as a set of principles that explain how we perceive and organize this huge amount of visual stimuli. Rather than perceiving elements separately, our brain organizes patterns, objects and shapes into whole forms that we can understand. In particular, our visual system processes vast amounts of information in its environment. The perceptual process enables us to perceive the world through our senses of sight, smell, sound, taste and touch. In this first article, Jon Hensley will take a look at how the principles of similarity and proximity work, and look at real-world examples to illustrate them in use so that you can begin to use similarity and proximity to create both relationships and differences between elements in your designs. bright, thick lines or dominant colors) to create a strong perception of grouping.Understanding how to use similarity and proximity to affect the relationships between elements in your work will help you create designs that enable easier organization and improve the usability of your work. Be aware that it does not take a strong enclosure (e.g. This principle is exhibited frequently in the use of borders and fill colors or shading in tables and graphs to group information and set it apart. This enclosure causes the objects to appear to be set apart in a region that is distinct from the rest of what we see. This technique can be useful for encouraging comparisons of any data in various places, such as order count, order size, and order revenue.Ī group of objects can be enclosed by anything that forms a visual border around them (for example a line or a common field of color). For example, using the color green to represent revenue across various graphs. Even when data that we wish to link resides in separate locations on a dashboard, the principle of similarity can be applied to establish that link. This principle works especially well as a means of identifying different datasets in a graph. We associate categorical variables to attributes such red color for loss, green color for profit, triangles for cats, etc. Objects of the same color, size, shape and orientation belong to the same group, right? The tendency of how we group things according to these factors or attributes are also part of Gestalt Principles. People, especially designers who understand these principles, can develop visuals that communicate information in the most effective ways. The Gestalt Principles consist of several principles that describe how the human brain sees visual information, namely – proximity, similarity, continuity, closure, connection, and enclosure. It refers to the patterns that you perceive when presented with a few graphical elements. Gestalt means “unified whole” in English and is generally associated with the idea that the whole is greater than the sum of its parts. You may be aware of it or maybe not, but every time you’re doing data viz, you definitely need to apply Gestalt Principles. Understanding why certain data visualization techniques work better than others has psychological roots. What’s the connection between these two ideas? Becoming good in data visualization requires the acquisition of foundational knowledge. Every person who’s very good at something started somewhere that laid the foundation of their expertise. Data visualization is not just about transforming data into understandable and good-looking charts.
