Data Visualization

Data visualization is a discipline within computer science that focuses on the graphical representation of information and data to communicate complex ideas clearly and efficiently. By using visual elements like charts, graphs, and maps, it transforms large and complex datasets into an accessible format, enabling users to more easily identify trends, patterns, and outliers. This field merges principles from computer graphics, data analysis, and human-computer interaction to create powerful tools that bridge the gap between raw data and human insight, facilitating exploration and storytelling.
