3 Simple Ways to Make Your Data Visualizations Clearer

In the fast-paced world of online content, data visualizations have to work hard. They need to be clear, concise, and immediately understandable—especially for audiences scrolling on mobile. Small design missteps can easily distract from the story you’re trying to tell.

Here are three simple but powerful tips to help your charts and graphics cut through the noise.

1. Simplify Labels and Numbers

One of the most common problems we see is label clutter. When space is tight—especially in charts with many small values—overly detailed labels can overwhelm the visual. This happens when creators use too many decimal places or insist on listing full official names for countries or companies.

Ask yourself:

  • How precise does this really need to be? For example, is 213.456 million necessary, or will 213M do the job?
  • Is brevity clearer? Instead of spelling out Democratic Republic of the Congo, could you simply use DRC?

Small tweaks like this can make your graphic cleaner and easier to digest.

2. Focus on One Main Chart

It’s tempting to try to tell your whole story in one big graphic. In fact, a decade ago, it was still fairly normal to create expansive long form infographics (like this classic Visual Capitalist post on Jade). But today, attention spans are shorter, and most content is consumed on small screens. You need to get your point across quickly.

Trying to show two or three charts in the same space often dilutes your message. If you must include extra charts as supporting data, either:

  • Give one chart clear priority and design the rest as secondary, or
  • Split the information into a slideshow or separate visuals.

A single, well-executed chart will have more impact than several competing for attention.

3. Save the Context for the Caption

Some data-driven stories spark a lot of questions and deserve deeper explanation. But cramming paragraphs of text into the visual and title itself—especially for mobile audiences—makes it instantly less shareable.

Instead, provide just enough context in the graphic so it’s still understandable if shared on its own. Then, use the caption, article, or accompanying post to offer the full background and nuance.

This approach keeps your visuals clean, while still ensuring that those who want more detail can get it.

The Bottom Line

Clarity is your best friend in data visualization. By simplifying labels, focusing on one main visual, and moving extra context to supporting text, you can make your graphics more effective, accessible, and shareable—without losing any of their storytelling power.

Learning From Top Posts on Voronoi

Why do people like what they like?

It’s an age-old question that even the most experienced designers and storytellers grapple with as they publish their work. The world is a patchwork of aesthetic preferences, and sometimes contradictory visual language. Simply put, there’s no easy answer. As with most endeavours, the most successful practitioners are great at pattern recognition. They experiment a bunch, see how people react, and adjust their approach accordingly.

In the modern world, the real heavy lifting of pattern recognition is now done by algorithms. The great voting machines on each platform are each their own Darwinistic systems, choosing specific content and elevating it above all others based on the reactions of millions of people. Voronoi is not the size of Meta, but our voting machine–powered by you!–still elevates some data stories to the top.

Here are the eight top performing posts of all time on Voronoi:

What can we learn from these top data stories? Are there universal attributes or potent design tricks that creators can use in their own work? We’ve identified a few key commonalities. Let’s dive in.

Attributes of Top Data Stories

1. Universality

In order to become one of the most popular graphics, the topic needs to have broad appeal. The topics in the examples above–personality traits and death–apply to every human being on Earth. Of course, these graphics are supported by strong visual concepts.

The iconic hourglass design created by Our World in Data was actually inspired by a previous design by Oliver Uberti, an author and former senior design editor for National Geographic. Now, it’s a bold move to recreate a design from somebody who’s so accomplished in their field, but OWiD put their own spin on the concept that added value and exposed a wider audience to this fascinating dataset. There are two keys to remixing an existing design, 1) add value, and 2) generous attribution to the original creator.

2. Intuitiveness

The most popular data stories spread far and wide, reaching audiences around the world. The most effective graphics don’t require too much explanation or text labels to get their point across.

In the graphics above, there are visual cues that help the viewer understand what’s being shown, even before they’ve read the title or labels. Not every concept lends itself to such a clear visual hook, but when it does, take advantage.

3. Tap into Big Trends

Not every major societal trend is interesting, but some do capture people’s attention and make them feel something (anxiety, excitement, anger, etc). Over the years, the surging popularity of Elon Musk has made people feel all kinds of emotions, from excitement about new technologies to revultion and amusement at his actions and statements. The point is, people feel something about him, which trumps indifference every single time.

In recent years, the struggle for dominance between the U.S. and an ascendant China has been a trend many are watching closely. Both of the graphics above tie directly into this narrative which people have strong feelings and opinions about. Note the bold and strategic use of colour here.
