Data Visualization

Definition

Data visualization is the graphical representation of information and data, using visual elements like charts, graphs, and maps to make complex data more accessible, understandable, and usable. It plays a crucial role in interpreting the vast amounts of data generated by smart home devices and the Internet of Things (IoT), allowing users to quickly grasp trends, patterns, and anomalies in their environments. By transforming raw data into visual formats, data visualization enhances decision-making processes and improves user experiences.
