Data visualization is more than just charts and graphs; it's a nuanced art form demanding careful consideration of audience, purpose, and narrative. Effective visualizations prioritize clarity and insight, requiring intentional design choices regarding color palettes, typography, and layout, similar to composing a painting or musical piece. Just as artistic masterpieces evoke emotion and understanding, well-crafted data visualizations should resonate with viewers, making complex information accessible and memorable. This artistic approach transcends mere technical proficiency, emphasizing the importance of aesthetic principles and storytelling in conveying data's true meaning and impact.
The article "Visualizing Data Is an Art – We Should Treat It Like One" posits that the process of data visualization is not a purely scientific endeavor, but rather a nuanced craft that requires artistic sensibilities and thoughtful consideration of aesthetic principles, much like painting, sculpture, or music. The author contends that while technical proficiency and accuracy are fundamental requirements for effective data visualization, they are not sufficient in themselves to create truly impactful and insightful visuals. Instead, the article emphasizes the crucial role of creativity, intuition, and an understanding of how visual elements can be leveraged to communicate complex information effectively.
The piece elaborates on this concept by drawing parallels between the creation of a data visualization and the artistic process. It argues that just as an artist carefully selects their colors, composition, and brushstrokes to evoke specific emotions and convey a particular message, a data visualizer must similarly make deliberate choices about chart types, color palettes, typography, and layout to guide the viewer's understanding and highlight key insights. Furthermore, the author suggests that a successful data visualization, like a successful piece of art, should be engaging, memorable, and capable of sparking curiosity and further exploration in the audience.
The article underscores the importance of narrative in data visualization, emphasizing that data should not simply be presented, but rather woven into a compelling story that resonates with the viewer. Just as a painter uses their canvas to tell a story, a data visualizer should use charts and graphs to narrate the insights hidden within the data, providing context, highlighting relationships, and revealing patterns that might otherwise remain obscured. This narrative element, the author argues, transforms a simple presentation of data into a persuasive and insightful communication tool.
Moreover, the article advocates for a more iterative and experimental approach to data visualization, encouraging practitioners to embrace the process of exploration and refinement, much like an artist experimenting with different techniques and mediums. The author suggests that the best data visualizations often emerge from a process of trial and error, where different approaches are tested, feedback is incorporated, and the visualization is gradually honed to its most effective form. This iterative process, the article concludes, allows for the integration of both analytical rigor and artistic intuition, resulting in visualizations that are not only accurate but also aesthetically pleasing, engaging, and ultimately, more impactful. By embracing the artistic aspects of data visualization, the author believes we can unlock the full potential of data to inform, persuade, and inspire.

HN users largely agreed with the premise that data visualization is an art, emphasizing the importance of clear communication and storytelling. Several commenters highlighted the subjective nature of "good" visualizations, noting the impact of audience and purpose. Some pointed out the crucial role of understanding the underlying data to avoid misrepresentation, while others discussed specific tools and techniques. A few users expressed skepticism, suggesting the artistic aspect is secondary to the accuracy and clarity of the presented information, and that "art" might imply unnecessary embellishment. There was also a thread discussing Edward Tufte's influence on the field of data visualization.
The Hacker News post "Visualizing Data Is an Art – We Should Treat It Like One" (linking to perthirtysix.com/visualizing-data-is-an-art) generated a modest discussion with several insightful comments.
One commenter highlighted the crucial distinction between exploratory and explanatory data visualization. They argued that exploratory visualization serves the data scientist in uncovering patterns and forming hypotheses, while explanatory visualization aims to communicate those findings effectively to an audience. This distinction emphasizes the different skillsets and goals involved in each type of visualization. They further noted the article's focus primarily on the explanatory side, which resonates with the "art" aspect of the title, as communicating insights effectively often requires careful aesthetic and narrative choices.
Another commenter agreed with the article's premise, stressing the importance of considering the audience when designing visualizations. They pointed out the frequent disconnect between technically sound visualizations and their effectiveness in conveying information to non-technical audiences. Clear communication, they argued, should be the primary objective, even if it necessitates simplifying or omitting certain data points.
A different commenter brought up the frequent misuse of data visualization for persuasive purposes, rather than objective representation. They cautioned against manipulating scales, choosing misleading chart types, or cherry-picking data to bolster a specific narrative, emphasizing the ethical responsibility of data visualizers to present information fairly and accurately.
One user shared a personal anecdote, recalling a colleague skilled in data visualization whose work significantly improved the clarity and impact of their team's presentations. This anecdote served as a practical example of the value of treating data visualization as a specialized skill.
Another contribution highlighted the role of tools in data visualization. While acknowledging the importance of artistic skill and judgment, they emphasized that the right tools can greatly enhance the efficiency and quality of visualizations, enabling practitioners to focus on the creative aspects rather than technical complexities. They pointed out that tools alone are not enough; the art lies in using them effectively to craft compelling narratives from the data.
Finally, one comment brought up Tufte's work, connecting the article's argument to Tufte's principles of maximizing the "data-ink ratio" and minimizing chartjunk. This comment reinforces the idea that effective data visualization involves careful consideration of visual elements and their contribution to conveying information.
In summary, the comments on the Hacker News post generally agreed with the article's premise, emphasizing the importance of audience awareness, ethical considerations, the distinction between exploration and explanation, and the role of both artistic skill and appropriate tools in effective data visualization. The discussion, while not extensive, provided valuable perspectives on the topic.
