Data visualization: The visual depiction of numerical data using different graphs, charts, and maps is known as data visualization. It's critical to follow specific data visualization best practices since they're fundamental in comprehending vast volumes of data. You will become a more successful communicator if you visualize your material using several graphical ways. Data visualization is a valuable technique for organizing your data for various sectors, from marketing to finance. On the other hand, specific rules to follow may result in a more accurate depiction of your data and a more effective transmission of the message you're attempting to communicate. Here are seven data visualization best practices to help you display data successfully and present it in an aesthetically beautiful and readily understandable way. 7 Best Practices for Data Visualization

The Benefits of Using Data Visualization Techniques

Before we begin, it's critical to understand why adhering to these ten data visualization best practices is vital. As previously said, data visualization is the process of turning facts, figures, and statistics into an aesthetically consumable graphic. However, there are specific recommendations to follow to guarantee that your data is as simple to grasp as you want it to be. These top ten data visualization best practices can help you create visually attractive and thorough charts, graphs, infographics, and more.

1. Determine Who You Want to Reach

Identifying who you're showing the data for, i.e., the target audience, is the first stage of inefficient data visualization and communication. This might assist you in customizing your approaches and methods for a specific audience. Marketers, corporate executives, social media managers, entrepreneurs, educators, students, and non-designers are some examples of possible target audiences. To ensure that everyone is on the same page, you may build a graphic to identify and represent your target audience. The way you show data must be clear and intelligible to the target audience for them to digest it quickly. Problems arise when the image's interpretation differs significantly from the conveyor's intent since mixing and matching representations muddles things. Early in the design phase, it's critical to identify the target audience and present the visualization's fundamental idea. This goal should be reflected in the visual's graphic design. 7 Best Practices for Data Visualization Although those familiar with the process may recognize the statistics in your visualization, others unfamiliar with the information may find it difficult to separate the facts from the data if the data is not displayed and clearly.

2. Ascertain that your data is error-free

Before you transform your raw data into a graphical representation, be sure the dataset you're using has been properly cleansed. The act of weeding out any irregularities or inconsistencies in your dataset is known as data cleansing. Before you utilize the data for another reason, you must go through this procedure since the existence of these flaws might distort the findings of your data interpretation. If you want to publish a figure in a journal, make sure your calculations are correct and that all critical information is shared with a larger audience. Because the goal of this scenario is to explain the theory, student audiences need special care. In such a scenario, you'll need to go further to ensure that the concept is fully grasped. Because you must build a basic, probably tentative graph that illustrates the most crucial feature of your study, a broad audience might be the most demanding audience. 7 Best Practices for Data Visualization

3. Choose the Correct Chart- Data Visualization

7 Best Practices for Data Visualization Once your data is clean, you may choose the style of graph or chart that will most effectively and efficiently express the essential information in the dataset. As you can see from the following points, there are many different forms of information that various charts may represent: Tables can organize a lot of data, but they may also confuse consumers looking for high-level trends. Line graphs show the interaction between two or more variables by measuring fluctuations or patterns across time. Bar charts compare and contrast the quantities and totals of various categories. Scatter plots show the relationship between two variables shown along two axes, with the pattern of the associated dots indicating a connection. Different areas of one data set are evaluated using pie charts and donut charts, simply a pie chart with a hole in the center. Individual values in the matrix are translated as color in heatmaps, which visually represent the data. Natural Language Generation (NLG) is a way of producing natural language via natural language processing. It may represent information in text form graphically and translate data.

4. Make Effective Chart Labels

7 Best Practices for Data Visualization Graphs and charts may help us rapidly see trends in our data. On the other hand, labels are the most excellent approach to express specific values that may be significant graphically. You can't explain everything with only the figure, whether you're discussing an experimental setting, introducing a new model, or presenting new data. This is why your figure should always be accompanied by a caption. The caption explains how to understand the image and adds accuracy to what can't be conveyed physically. This is similar to clarifying an oral presentation or in front of a poster, with the difference that you should prepare ahead of time for the questions that will be asked.

5. Highlight the Crucial Points

7 Best Practices for Data Visualization The audience must follow the narrative you attempt to tell by looking at your chart in data visualization. This is why using visual signals like reference lines or highlighted trends to draw the reader's attention is so important. Visually, humans can take a greater quantity of information. Our gaze is attracted to symbols that provide essential information in a single glance. We look for patterns because it's tough to understand the picture if the designs are chaotic or nonsensical. Make sure that the sequence or manner in which you present the facts makes sense to your audience to draw on these human characteristics. You may utilize numeric, alphabetical, or sequential data. If you're attempting to convey information in a language that reads from left to right, for example, make sure your data visualization follows suit. Make that the arrangement of the graphs in a single infographic is correct and the relationships between the data are apparent. This prevents the audience from becoming confused as they go from one chart to the next.

6. Select the Most Effective Dashboard

To get the most out of the data visualization, you need to know what kind of dashboard you're giving your audience. You may provide users with three different types of dashboards.


These dashboards are meant for C-Suite executives and department heads, and they provide a detailed examination of the organization's KPI metrics success. They're created to answer common queries that every CEO would want to know, such as how many MQLs the company has in its sales funnel. How much did they earn the previous month? The primary purpose of this dashboard is to deliver immediate information.


These dashboards are a lot of fun to use. They let developers and members of the technology or analytics team experiment with data to solve stakeholder issues.


These dashboards are put up with often updated information that meets a particular criterion of daily operations and comprises data that isn't a high-level perspective. It's more about presenting information that isn't often seen by upper management.

7. Make Sure Your Chart Is Accessible

Ensure uniformity and clarity in the design features of your chart, such as axis or grid lines, to improve the overall readability of your represented data. Another critical factor is the text you choose. Although excessive use of language may be irritating, relying simply on images is insufficient. When using text, make sure it emphasizes essential facts—adding language when appropriate makes a tremendous impact, even though we're hard-wired to perceive patterns and symbols over words. Another important consideration is to keep your visualizations free of clutter and noise. Because data visualization is all about successful communication, it's critical to make sure your chart isn't cluttered with irrelevant information that detracts from the essential features. Final Words Processing, analyzing, and adequately displaying massive datasets has become a vital aspect in defining the trajectory of all professional tasks and operations. Data visualizations enlighten, explain, and persuade in various fields, including marketing, sales, and business development. Using the correct data visualization best practices can make all the difference in the world. By following the standards listed above, you can guarantee that your data visualizations are always readable, persuasive, and captivating. Read More: How Can Smart Data Discovery Help Your Business?
