How can multiple visualizations be organized in Tableau?

In Tableau, multiple visualizations can be organized by grouping them together into a cohesive dashboard. The speaker demonstrates this by working with four different visualizations, first labeling one as "enrollment total" and then planning to group all four visuals together for a more comprehensive view. This grouping feature allows users to combine related visualizations into a single display, making it easier for viewers to see connections between different data points. By organizing multiple charts and graphs together, Tableau enables more effective data storytelling and helps highlight important insights that might not be apparent when viewing visualizations separately.
