Data visualization is the process of representing data in a visual format such as charts, graphs, maps, and dashboards to make information easier to understand and interpret. Instead of analyzing large amounts of raw data in tables or text, visualization allows users to quickly identify patterns, trends, and insights through visual elements.
This technique is widely used in business, marketing, healthcare, finance, and technology to simplify complex data. Tools like Tableau, Power BI, and Google Data Studio help create interactive and dynamic visualizations that can display real-time data and allow users to explore information through filters and controls.
