Key idea 1 of 6

What’s in it for me? Create clear and captivating data visuals that drive action.

Data visuals are everywhere, but let’s be honest: many of them miss the mark. You’ve likely encountered charts overloaded with colors, confusing layouts, or cluttered details that make it nearly impossible to grasp the intended message. The problem isn’t a lack of tools – after all, anyone can create a graph with software like Excel. The real issue lies in how we approach the task. Few of us are taught to combine numbers with narrative, to transform raw data into clear, impactful stories.

In this Blink, you’ll learn how to create visuals that do more than present data – they engage, inform, and persuade. You’ll discover how to simplify your visuals, design for accessibility and aesthetics, and guide your audience’s focus using narrative principles. Armed with these strategies, you’ll be equipped to communicate your insights in ways that are both memorable and actionable.

Context drives effective data storytelling

Before you even start creating charts or visuals, success in data storytelling depends on something far more fundamental: understanding the context. Here’s a common mistake – sharing a comprehensive dataset with your audience when all they need is a clear takeaway. It’s tempting to present everything, but this overload can lead to confusion rather than insight. Instead, focus on the essential pieces of information your audience needs. This is where understanding the who, what, and how comes into play.

First, define who your audience is. Avoid vague categories like “stakeholders” or “general public.” Targeting too broad a group often results in diluted communication. Instead, narrow your focus to those directly impacted or who need to act on your data. Consider their existing knowledge, potential biases, and their perception of you as the presenter.

Next, clarify what you want your audience to do or understand. Is it to approve funding, adopt a strategy, or simply grasp a trend? Take a confident stance in recommending specific actions, even if it feels outside your comfort zone. A clear directive encourages your audience to engage with the material rather than passively observe.

Finally, determine how you’ll communicate. Whether it’s a live presentation or a detailed report, adapt your content accordingly. Live presentations allow for direct interaction and flexibility, while written documents should anticipate and answer potential questions, given their lack of real-time engagement.

As you structure your message, try boiling it down into a 3-minute story – a concise explanation of the issue, data, and recommended action – or distill it further into a Big Idea, a single sentence encapsulating your unique perspective and what’s at stake. For example, a 3-minute story could describe how a pilot summer program improved students’ perceptions of science, supported by survey data showing a 70 percent increase in positive attitudes, while a Big Idea might recommend continuing the program based on these results. Planning your communication using tools like storyboarding can also help you organize your thoughts and ensure your message flows logically.

By starting with the context, you’ll guarantee your visuals aren’t just clear but impactful, guiding your audience toward understanding and action. In the end, thoughtful preparation transforms data into a compelling story that resonates.

Choose a visual that communicates effectively

Picking the right visual is essential if you want to effectively communicate your data’s message. But first off, ask yourself if a visual is even necessary. If, for example, you have just one or two numbers to share, why use a graph at all? Instead, a simple, bold statement like “20 percent of children had stay-at-home moms in 2012, compared to 41 percent in 1970” can have far greater impact. Visuals are powerful, but their effectiveness depends on selecting the one best suited to your data and message.

Start by understanding the differences between tables and graphs. Tables engage the verbal system, requiring viewers to read and compare values; this makes them ideal for presenting detailed information to a mixed audience. However, they rarely work well in live presentations, where attention is better directed through summarized visuals. To make tables easier to read, minimize heavy borders and shading so the data takes center stage.

Simplify visuals to focus your message

Ever seen a chart overloaded with gridlines, excessive labels, and colorful but irrelevant decorations? Instead of guiding the viewer to a clear takeaway, visuals like this create confusion and mental fatigue. This happens because every element in a visual demands mental effort from your audience. The more unnecessary elements you include, the harder it becomes for viewers to process the information you’re presenting. Clutter – those extra lines, borders, markers, or redundant text – can make your message feel convoluted and overwhelming. Just think of a sales trend chart. What should be simple to understand becomes frustrating to decipher if it’s crowded with bright colors, heavy gridlines, or a legend where direct labels would suffice.

Cognitive load is the mental energy required to process information. While some level of effort is necessary to understand data, too much can lead to frustration and disengagement. Clutter plays a big role here, as it makes visuals appear more complicated than they need to be. By removing unnecessary elements, you can minimize this mental strain and allow your audience to focus on the insights that matter.

Direct your audience’s attention with strategic visual cues

Your viewers don’t have unlimited cognitive resources, so your design choices should make absorbing information as effortless as possible. Visual cues have the power to precisely direct people’s attention – often before they consciously realize it. For example, consider how much faster you can count a specific number in a grid when it’s highlighted in bold red compared to when it’s left unmarked. This instant recognition is made possible by preattentive attributes – design elements that your brain processes almost automatically, like size, color, and layout.

Preattentive attributes can serve two main purposes: drawing immediate attention to key elements and creating a visual hierarchy that guides the audience through your information. Used effectively, these tools can help you lead your audience’s focus exactly where you want it to go.

Design principles can elevate your data visualization

In 1933, Harry Beck reshaped how people navigate London by rethinking the Underground map, prioritizing clarity and ease of use over geographic precision. His design remains iconic because it focuses on what users need most: straightforward, functional visuals. The same principle applies to data visualization – good design makes complex information accessible and engaging for any audience.

Affordances, a concept borrowed from design, are about making the purpose of an object self-evident. In the realm of data visualization, this means designing elements that help the audience seamlessly interpret and engage with the information you’re presenting. For example, just as a handle signals pulling or a button suggests pressing, your visualizations should use intuitive cues – like a clearly highlighted trend line or well-placed labels – to communicate their purpose. When affordances are thoughtfully incorporated, your design becomes almost invisible, allowing the data’s message to shine without your audience consciously analyzing how to understand it.

Make your data memorable through storytelling

When people hear the story of Little Red Riding Hood, most can recall its twists and turns years later. Why? It’s not the facts about the characters or events alone – it’s the narrative structure that embeds the story in our memory. This concept applies to communicating with data too: presenting numbers and charts alone won’t engage your audience. Instead, crafting a clear story with a beginning, middle, and end ensures your message resonates, is remembered, and inspires action.

Humans are natural storytellers, and this skill has been central to how we communicate ideas for centuries. Borrowing from Aristotle’s three-act structure – setup, conflict, and resolution – gives us a framework for creating compelling narratives. Begin by setting the stage and introducing the problem or imbalance your audience cares about. Develop the middle by exploring the stakes, providing relevant data, and proposing actionable solutions. Conclude with a resolution that includes a clear call to action.
