definition• Data visualization (or more appropriately, information
visualization) has been defined as the use of visual representations to explore, make sense of, and communicate data.
• Since, information is the aggregation, summarization, and contextualization of data (raw facts), what is portrayed in visualizations is both the information and the data.
