Data representation is the process of organizing and presenting data in a meaningful way that can be easily understood and utilized by humans or machines. It involves converting raw data into a visual or symbolic form that is more informative and easier to interpret. This can include using graphs, charts, tables, diagrams, symbols, or other visual aids to communicate complex data sets. Data representation plays a crucial role in data analysis, data visualization, and data communication, as it helps to identify patterns, trends, and relationships within the data. It is an important aspect of data science, computer science, and information technology.
