**What does "data visualization" refer to in data analysis?**
**Data visualization** refers to the graphical representation of data and information. It enables analysts to present complex data sets in a visual context, such as charts, graphs, and maps, making it easier to identify patterns, trends, and outliers. By transforming raw data into visual formats, data visualization aids in better understanding and faster decision-making. Effective data visualization uses techniques like infographics, interactive dashboards, and storytelling with data, enhancing the ability to communicate insights clearly to both technical and non-technical audiences, thus driving informed actions.
