Let me show you how to Create a Card in Power BI with an example. A card is useful to display a single number (or metric value). For example, If we want to track the total orders, total sales value, or total quotations we sent, we can use this Card visualization.
For this Power BI Card demo, we will use the SQL Data Source that we created in our previous article. So, Please refer to Connect to SQL Server article to understand the Power BI Data Source.
