The Value of Data Visualization for Data Science Professionals
“A picture is worth thousands of lines of data,” a slight modification to the original Frederick R. Barnard’s adage- “A picture tells a thousand words.” Visualization is most appealing to the human brain, and this is what makes data visualization a fundamental skill for a data science professional.
Data visualization is a technique where abstract statistical and numerical information is translated into attributes of vision – color, shape, size, position, or motion - to communicate, analyze, and arrive at important business decisions. Data visualization helps organizations translate the humongous data into a form that our brains can interpret easily, get a quick sense of the story, make decisions, and plan for the future.
Verified Market Research™ reports that the data visualization tools market will be worth USD 11.79 bn globally by 2028, growing at 10.4 percent CAGR.
Data visualization: The what and why for an organization
Human brain can process images 60,000 times faster than texts!
Data visualization is a skill that all organizations have started to appreciate. They look up to data scientists to explain the processes and results more easily with visualization. It is useful for data cleaning, structure data, detecting outliers, identifying trends, spot patterns, understanding clusters, evaluating output, and presenting results.

In an organization, a data science professional, or a data scientist, in particular, have to simplify a project to make it understandable for the stakeholders, business leaders, and clients. To get a ‘buy-in’ for a project, data visualization will be beneficial. It could involve a simple usage of PowerPoint presentations, Jira, or Lucid charts. We have covered some of the different types of data visualization used by professionals here.

So, data visualization is becoming a critical skill for today’s professionals.
Data visualization: A critical skill for data science professional
The goal is to turn data into information, and information into insight ―Carly Fiorina
Data visualization skill is a must to have to present the insights derived from data to fellow workers, non-technical team, stakeholders, and business holders. With this skill, one can –
Make data more accessible and less confusing
Tackle business problems and find solutions in a timely manner
Use pie charts, scatter plots, line plots, heat maps, bar charts, etc.
Manage humongous business data in a clear and cohesive manner
Make data work for the organization
With data visualization, data science professionals can emphasize on data, make large datasets coherent, compare different pieces of data, reveal data at multiple levels of detail, and think about the substance of the information. In brief, complicated processes and business results can be explained easily with it.
Moving forward, let’s understand the tools data scientists and big data analysts use. Here are a few of the popularly used data visualization tools.

Case study 1: Making data actionable at Uber
1. UBER USES DATA VISUALIZATION TOOLS
Uber handles billions of GPS points every day posing a typical challenges for real-time mapping visualization. You can see the data visualization crafted by Uber’s big data engineering team to show traffic per street with and without UberPool. It clearly demonstrates their ability to make cities smarter by reducing traffic.

This map shows the risk level of attending an event considering the event size and location. The risk level is nothing but the estimated chance that there will be at least one COVID -19 positive individual at an event.
One can reduce the risk by wearing a mask, maintaining social distancing, and gathering outdoors in smaller groups.
As industries accelerate their digitalization process, they are tapping the power of data analytics at every step as they can. In this effort, if industries can pair it with data visualization, it can help them to become more focused on business decisions.
However, there may occur advanced analytics issues, predictive model errors, or misuse of statistics when there is a lack of expertise. As a result, industries seek data science professionals who can explore their business data with full confidence and avoid errors.
