1. create relationhip between two tables using id column 

2. use drop down menu on name column and use count distinct as shown below

3.  use the dropdown menu of id column and select show items with no data as shown below 

If there are blank values in visuals, they will be hided by default. It is by design for Power BI. So, after creating relationships, you need to turn on the option "Show items with no data".
