What role does the Card visual play in Power BI when troubleshooting individual variables?

The Card visual in Power BI is specifically designed to showcase a single, prominent value, making it ideal for examining individual variables. This feature allows users to clearly see key metrics without distraction, which is particularly useful during troubleshooting when a focused analysis of a specific data point is required.

By using the Card visual, analysts can rapidly interpret the values associated with an individual variable, isolating them from more complex datasets and visualizations. This clarity assists in identifying issues or underlying patterns, supporting decision-making based on singular data points.

While other visuals can provide insights on broader trends or summarize data comprehensively, the Card visual stands out for its simplicity and emphasis on individual values, which is crucial for in-depth troubleshooting efforts.
