How do I make my data visualization more interesting, dynamic, relevant, and well-received by diverse audiences? For anyone developing a visualization—whether you’re a newcomer or seasoned data analyst—these questions are top-of-mind because you want to make it great. If they’re done well, visualizations tell an interesting story. They can also shine a light on hidden information and details that you wouldn’t uncover in a spreadsheet, bar chart, or pie graph.

Before jumping to specifics, think about what you want to accomplish with the visualization, which helps you decide what data to include.

Ask yourself these questions:

  • Who is my audience?
  • What questions do they have?
  • What answers am I finding for them?
  • What am I trying to say?
  • What other questions will my visualization inspire or what conversations may result?

When you’re ready to dive in and create, these tips and techniques will make your visualization intuitive and interesting so it’s digested quicker, easier, and the intended messages come through clearly, leaving viewers with specific, helpful takeaways.

1. Choose the right charts and graphs for the job

One size does not fit all so carefully consider and choose the right format for your visualization that will best tell the story and answer key questions generated by data—all of it connecting with your main purpose. Sometimes even combining related charts is helpful; it can fuel deeper exploration that leads to helpful business insights and answers that driven action.

What are popular formats?

  • Bar charts are effective at comparing categories within a single measure and one of the most common data visualizations. They’re especially effective when you have data that can be split into multiple categories.
  • Bullet charts show progress against a goal by comparing measures and were designed to replace dashboard gauges, meters, and thermometers.
  • The line graph connects several distinct data points, presenting them as one continuous evolution. The result is a simple, straightforward way to visualize changes in one value relative to another.
  • Histograms and box plots show where your data is clustered and can compare categories.
  • Maps are a no brainer for visualizing location-specific questions or aiding geographical exploration.
  • Pie charts are powerful for adding detail to other visualizations, but aren’t as effective on their own. In fact, every year on Pi Day (March 14), data scientist Kaiser Fung and his colleague find a pie chart and remake it into a more suitable version, as their way of protesting against flagrant overuse.

2. Use predictable patterns for layouts

Humans are visual creatures by nature. Our eyes are drawn to indicators that tell us important information at a glance. We naturally seek patterns, and if patterns are random or don’t make sense, it’s very difficult to understand what the visualization conveys.

To capitalize on these human tendencies, make sure the order or format in which you present data makes sense to viewers; whether it’s numeric, alphabetical, or sequential. A simple example: if you are communicating in a language that reads left to right, then orient your visualization to adhere to that convention. If you’re using multiple graphs, make sure the order is consistent and connections between the data are clear. You don’t want your viewer’s to get lost as they follow one point to another quickly and easily.

3. Tell data stories quickly with clear color cues

Color is important. It can convey so much without using words. However, there’s a delicate balance to using color; keeping it simple is best. Use color to highlight and accentuate the information. Too many colors will create a cacophony, while using a single color or too many shades of one color can cause the data to blend.

Color association matters, too. Use intuitive colors that make sense to the viewer so they process the information faster. If you’re working with temperatures, use red to indicate heat and blue for cold. And how you use colors also has serious effect. It’s helpful to show consistency across values or to highlight contrasts in the data.

4. Incorporate contextual clues with shapes and designs

Context helps us decipher information at first glance instead of sitting and scrutinizing it. Subject matter shapes can tell a compelling story. For example, the above chart on endangered species in Africa tells us at a quick glance what animals are endangered and how vulnerable they are. Instead of using bar charts with values, where each animal is minimized to numbers and text that make the data and the viewer get lost, using the animal silhouettes makes it far more interesting and intuitive.

5. Strategically use size to visualize values

Size can help emphasize poignant information and add contextual clues. In the previous visualization, the endangered animal shapes mimic how large an animal is in relation to others. However, size can also denote scaled values. Instead of using color, shape size can adjust based on data values.

Using size to indicate values also works well with maps. When you have several data points in the same size on a visualization, they blend together and it’s difficult to differentiate values. Making size relative with value, and adding color as another marker, the visualization is easier to navigate as depicted in this example.

6. Apply text carefully and intentionally

Lastly, your choice of text can improve your visualization, whether it’s the kind of text you use or even how much. While text is distracting when there’s too much or if it’s not organized in a visually pleasant way, sometimes relying only on visuals doesn’t suffice. When using text, make sure it points out important details—like individual contributions of the Beatles members to the signature songs and albums that they released at the height of their popularity. While we’re hardwired to process patterns and images over words, applying text where it really counts can make a major difference.

Here are a few other guidelines to help take your visualizations from good to great:

  • Place the most important view at the top, or in the upper left corner. Your eye is usually drawn to that area first.
  • Limit the number of views in your visualization to three or four. If you add too many, the big picture is lost in the details.
  • If you have multiple filters, try grouping them together. A light border around them gives a subtle visual cue that they have shared features.
  • Interactivity can make the difference between a horribly-confusing visualization and an all-star analysis. You need to guide the story, encourage exploration, and when building in interactivity, make sure viewers know that they can engage with it—perhaps offering subtle instructions for them.
