The significance of data visualization lies in its ability to transform complex data into easily interpretable visual formats like charts and graphs. This process helps communicate insights and patterns effectively, enabling both technical and non-technical audiences to understand trends, correlations, and anomalies within the data. By enhancing comprehension, data visualization supports better decision-making and facilitates storytelling with data. It is essential for businesses to convey findings and make actionable recommendations based on their analysis, leading to improved outcomes and strategic planning.
