The dashboard includes 10 pre-made visualizations from a sample movie dataset, allowing users to see how various visualizations are made in Charts. New users can access the dashboard by choosing the "Explore with Sample Data" option, while experienced users can add it to their existing charts with a single click. The dashboard provides an opportunity for users to break down pre-made visualizations and learn about the capabilities of Charts, including filtering capabilities and making custom charts. By exploring the sample dashboard, users can find inspiration for visualizing their own data, from monitoring performance metrics to creating engaging visuals and driving business decisions.
