What is the purpose of Lasso Selection in data visualization?

Lasso Selection is a valuable tool in data visualization, particularly for allowing users to interactively select a group of field values on a chart at once. This method enables users to draw a freeform shape around the data points they want to select, making it much more efficient to focus on multiple related data points simultaneously.

By using Lasso Selection, users can easily analyze subsets of data, compare characteristics, and derive insights from clusters without having to click on each individual point. This capability enhances the interactivity and depth of analysis in visual data representation, streamlining the process of exploring data relationships and patterns.

The other choices list functionalities that are not the primary focus of Lasso Selection. Single values, specific areas, and highlighting a single point represent more traditional forms of selection and interaction that do not take advantage of the grouping features that Lasso Selection offers.
