Data visualization is the visual representation of data by using graphs, charts, plots or information graphics. Data visualization is also becoming increasingly interactive, allowing viewers to engage with the representation for deeper analysis and insights or a shifted perspective. Regardless of the medium, data visualization serves an important purpose: communicating key trends and opportunities to stakeholders for effective decision-making. Data visualization makes complex information more accessible.
Effective Data Visualization
When presented with a straightforward report, our eyes can’t help but glaze over the numbers; data visualizations, on the other hand, communicates its significance faster and easier, providing the viewer with the right “ah-ha” moment. However, this is only when data visualizations have been well-designed—without the right considerations, data visualizations risk being just as confusing, simply in a new format.
Successful data visualizations will allow the analytic content to inform the design, above all else. This means first identifying a goal, or questions that the data visualization should answer, in order to understand how the design should take shape. For example, does this data visualization clearly indicate the relationship between these data points? Does the data visualization represent the quantities accurately? Addressing these questions will help determine which format, style, and color is best for your data visualization.
Upstream Considerations for Data Visualization
Since data visualizations are only as impactful as the data they represent, ensuring that this data is of the highest quality is extremely important. This begins higher up the data chain, when ingesting and preparing data for analysis. For example, Trifacta Wrangler helps users with data visualization early on through complete histograms that detail the raw contents of their data. This empowers a non-technical users, who typically design data visualizations, to gain insight sooner and better predict what and how they need to communicate.
Data Visualization for Your Business
There’s no question that effective data visualizations will allow your business to better understand its data and make better decisions faster. However, when creating various data visualizations, consider the full lifecycle of that data. Get involved earlier on through self-service data preparation to ensure that you’re working with data of the highest quality and not missing any unforeseen insights.
