Exploratory visualization primarily emphasizes discovering patterns, trends, and relationships within the data that may not be immediately apparent. The goal is to interactively explore the dataset, often allowing users to manipulate the visualizations, filter data, and analyze it from multiple perspectives. This helps in uncovering insights that can inform further analysis or hypothesis generation.

The other options present distinct focuses that differ from the primary aim of exploratory visualization. For instance, outlining predefined data findings is more aligned with explanatory visualization, which aims to present clear conclusions based on the data rather than delve into exploration. Describing the data succinctly usually involves summarizing key statistics or main characteristics, which is also not the core intent of exploratory techniques. Lastly, documenting research methodology pertains to outlining how a study or analysis was conducted, which is unrelated to the exploratory phase of data visualization where exploration of the data itself takes precedence.
