What is Data Visualization?
Data visualization is the graphical representation of information and data using charts, graphs, maps, and other visual tools. It allows individuals to quickly grasp complex patterns, trends, and outliers within a dataset. Beyond mere aesthetic appeal, effective data visualization serves as a bridge between raw data and actionable insights, making information accessible to both technical and non-technical audiences.

Visual tools like scatter plots and heat maps make it simpler to identify correlations and patterns within data. Recognizing these relationships can lead to more informed and strategic decision-making.
