Data Visualizations

Definition

Data visualizations are graphical representations of information and data that help to communicate complex ideas clearly and efficiently. They transform raw data into visual formats, such as charts, graphs, and maps, making it easier for audiences to understand patterns, trends, and insights. By utilizing data visualizations effectively, speakers can enhance their presentations and create a more engaging experience for their audience.
