What is Data Visualization?

Data visualization is the graphical representation of information using charts, graphs, dashboards, and maps. It helps businesses analyze large datasets and uncover patterns, trends, and insights for better decision-making.

Why Is Data Visualization Important?

Humans process images 60,000 times faster than text, with 90% of transmitted information being visual. This makes graphical data easier to interpret and retain. As businesses generate massive data daily, visualization tools help extract valuable insights quickly.

For instance, Internet users create 2.5 quintillion bytes of data daily, highlighting the need for efficient ways to analyze this information. Businesses use visualization to identify trends, optimize strategies, and improve performance.
