Learn data visualization with online courses and programs
What is data visualization?
Data visualization refers to the graphical presentation of information or data. Experts use data visualization tools to translate complex analysis into a format that others can easily interpret and understand.
Data is first collected and organized before it is run through various analytical tools and processes to uncover significant trends or anomalies. Rather than simply presenting numbers and values, professionals can use data visualization to transform their findings into a digestible, easily understood format.
Data visualizations can be used to explain a wide array of complex issues, ranging from pay disparities among genders to shifting demographics in particular locations to changes in climate over hundreds of years.¹ And there are many different types of data visualization formats, with varying levels of complexity. A simple line graph or bar chart may be the right choice for an audience who wants to understand topline findings about year-over-year revenue growth for a company. But for somebody interested in displaying how a company’s customer base has shifted over time based on location, they may find 3D modeling to be a more effective tool.
Data can be shaped in a variety of ways. Understanding how to use data visualization tools can be the key to successfully reaching your intended audience.
