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.
