Data Visualization Excellence - Best Practices for Research Communication and Analysis

Overview

Effective data visualization serves as both a powerful analytical tool and a crucial communication medium in research and professional practice. A visualization can give you the big picture, but what you see when you look at that picture and how you help others understand it requires careful consideration of design principles, audience needs, and communication goals.

Already, our analyses have drawn heavily on the visualization functionality that software like Tableau provides. For our own purposes, it's fine if these visualizations are a little rough. But what if you want to present your findings to others, in presentations or publications? At this point, you must pay considerably more attention to how you format and style your visualizations.

Fundamental Design Principles

Keeping It Simple and Straightforward

One key principle is to keep your visualizations simple and straightforward. Try not to overload them with information. For complex issues, a series of graphs that build on each other are often more valuable than a single visualization that tries to do too much.

Good visualizations must be accompanied by good explanatory text. If you need to explain specific issues and limitations, do so in a paragraph beside the graph rather than in the graph itself.

The Novel Visualization Problem
Tableau and other recent data analytics tools have introduced a range of novel and aesthetically pleasing approaches to data visualization. However, often your audience will not be familiar enough with these approaches to understand what you're trying to tell them. They can end up misreading the graph because they're distracted from the core information by decorative elements.

For instance, you may have seen word clouds, which have become popular in recent years. Many inexperienced data analysts have chosen to use this approach to show the relative prominence of key terms in their data, even though this form of visualization is fundamentally unscientific. It can even be misleading, because the human brain finds it very difficult to identify small differences in font size. A simple list of key terms, ordered by how frequently they occur, would be considerably more useful.

So, for the time being, we're disregarding some of the more novel visualization options that Tableau offers and focusing on established, scientifically sound approaches.

Media-Specific Formatting Considerations

Besides the audience for your visualization, it's important to consider where you'll display it. Online, slide and print presentations require different formatting approaches.

Print Publications

Digital Presentations
Your graphs might need high or low resolution, might be colour or greyscale and might be viewed at the reader's leisure or as part of a brief presentation. This all influences your choices of font sizes, colour schemes and visual complexity.

Especially when presenting to a live audience, it's best to assume that you're working with a very low-resolution data projector. It's a good idea to significantly increase the font size and choose contrasting colours so that even people in the last rows can see the information clearly.

Conclusion

Effective data visualization requires balancing technical capabilities with clear communication goals. The objective is not to create the most sophisticated or novel graphics, but to facilitate understanding and appropriate decision-making based on evidence.

Much great research has been undermined by poor visual presentations, while clear, honest visualizations can significantly amplify research impact. The key is understanding your audience, selecting appropriate techniques for your data and message, and maintaining rigorous standards for accuracy and accessibility.

As visualization tools become more powerful and accessible, success increasingly depends on thoughtful design decisions rather than technical implementation skills. The most important considerations are not what you can create, but what you should create to best serve your communication objectives.

The principles outlined here provide a foundation for creating visualizations that truly serve their intended purpose—whether for personal analysis, academic publication, business decision-making, or public communication. Remember that the goal is always to enhance understanding, not to impress with technical sophistication or aesthetic novelty.
