In today’s data-rich world, making sense of vast quantities of information is a critical challenge. The value of data lies not just in its volume but in the insights that can be drawn from it. Data visualization is the graphical representation of information and data, enabling viewers to understand patterns, trends, and outliers in complex datasets. By transforming raw data into visual form—such as charts, graphs, maps, or infographics—data visualization helps users see the meaning behind the numbers and make informed decisions.
