What happens when "Highlight Matches" is checked in circle pack visualization?

When "Highlight Matches" is checked in circle pack visualization, clusters that contain documents matching the specified filter criteria are prominently highlighted in orange. This visual distinction makes it easier to identify which clusters are relevant to the user's search or filter parameters, facilitating a clearer understanding of the data distribution and thematic content within the dataset. The use of color not only enhances visual appeal but also aids in quick recognition of important clusters, improving the overall effectiveness of data analysis in the visualization space.

Other options may suggest changes such as altering cluster sizes or formatting cluster names, but these do not accurately illustrate the function of the "Highlight Matches" feature in this context. Thus, highlighting clusters in orange serves a specific purpose that relates directly to enhancing data visibility and user engagement with the visualization.
