This post will review how the four most common Gestalt Principles in data visualization design (highlighted in bold above) can be used to enhance how people view and interpret your visual, and guide your analytical story. There are seven main Gestalt principles that have clear applications in data visualization. Additionally, they help your reader better organize and interpret charts and graphs and make sense of the information visually, with exceptional speed.Ĭheck out the viz below in it’s interactive form which shows descriptions for all seven Prinicples. So why is it important to understand these laws of perception when working in data visualization? Well, for one, they can help guide your decision making as you put together a graph or a dashboard. Gestalt principles, as well as pre-attentive attributes (which I’m not reviewing here), are methods by which we organize the world so that it’s familiar, makes sense, and is easy to process. So what does our brain do? It simplifies. The fact is that there is just too much for our brains to take in and if we did, we would be paralyzed by trying to interpret it all. If you are aware of optical illusions or the famous “gorilla in a crowd” study, you know that we often don’t process everything in our visual field. This is all to say that our brain often sees things different than what is actually present.
