What function does the plugin serve in the context of chart presentations in the canvas?

The correct function of the plugin in the context of chart presentations on the canvas is that it brushes or highlights charts based on the dimension value. This feature allows users to interact with the visual data more effectively by emphasizing specific aspects of the data relevant to the selected dimension. By highlighting charts, the plugin helps users quickly identify trends or anomalies related to that dimension, thereby enhancing data analysis and presentation capabilities.

The ability to brush or highlight offers an intuitive way to explore relationships and correlations among different data points reflected in the charts, making it easier for users to present their findings and insights. This interactivity is crucial for effective data storytelling, as it draws attention to significant data relationships that can drive discussion and analysis.

In contrast, the other functions listed do not align with the highlighted capability of the plugin. Creating new charts from scratch involves generating new visualizations rather than manipulating existing ones. Exporting the entire canvas to a file focuses on outputting the presentation rather than improving data interaction. Organizing charts into folders relates to data management rather than enhancing the presentation of data within the charts themselves.
