connection visualization

hello everyone!

in my DW i have three entities and to "connection table" between two of th the entities. also each instance of the entity has "grade" attribute.

i want to add my report a visualization that will show all the connections between entities, and also show the grade of eace entity.

can someone think about an idea to show it in the dashboard?

there is the networkNavigation visualization, but it shows the attribute of the connection (and not of the entity like i want), distance between two cities for example.

thank you very much!!
