Network chart with Multi-Parents

hello,

Is there any possibility to create Network charts with multi parents ?

I need to display a group organization, with subsidiaries, entities, detention links, holdings, etc. 

Some companies often have several parents instead of only 1 parent.

Do you know how I can do that ?

I already tried a little bit with following visuals : network Navigator, Social Network Graph, ZoomCharts Advanced Network Visual.

I imported some custom visuals but it doesn't meet my need

Thanks in advance !

Best regards
