How to create a family tree structure in Blazor Diagram?

In Blazor Diagram, you can create a family tree structure and auto-arrange nodes using automatic layouts. The Complex Hierarchical Tree layout organizes nodes in a tree-like manner where a child node can have multiple parents, extending the traditional hierarchical tree layout.

Please refer to the following code example for creating a family tree structure with DataSource in Complex Hierarchical Layout

Code Snippet:

//Specifies a complex hierarchical tree layout
<Layout Type="LayoutType.ComplexHierarchicalTree" LinearArrangement="true" @bind-HorizontalSpacing="@HorizontalSpacing" @bind-VerticalSpacing="@VerticalSpacing">
 </Layout>
 
//Defines a collection of objects representing a complex hierarchical structure
public object DataSource = new List<object>()
   {
       new ComplexHierarchical() { Id= "1",RelationShip="Dad",ImagePath="/diagram/images/people-circle26.png" },
       new ComplexHierarchical() { Id= "2",RelationShip="Mom",ImagePath="/diagram/images/people-circle0.png"},
       new ComplexHierarchical() { Id= "3",RelationShip="Brother",ImagePath="/diagram/images/people-circle23.png", ReportingPerson=new List<string>() {"1","2" }},
       new ComplexHierarchical() { Id= "4",RelationShip="SisterInLaw",ImagePath="/diagram/images/people-circle21.png",ReportingPerson=new List<string>() {"1","2" }},
       new ComplexHierarchical() { Id= "5",RelationShip="Sister",ImagePath="/diagram/images/people-circle16.png", ReportingPerson=new List<string>() {"1","2" }},
       new ComplexHierarchical() { Id= "6",RelationShip="BrotherInLaw",ImagePath="/diagram/images/people-circle33.png",ReportingPerson=new List<string>() {"1","2" }},
       new ComplexHierarchical() { Id= "7",RelationShip="Sister",ImagePath="/diagram/images/people-circle11.png", ReportingPerson=new List<string>() {"1","2" }},
       new ComplexHierarchical() { Id= "8",RelationShip="BrotherInLaw",ImagePath="/diagram/images/people-circle31.png", ReportingPerson=new List<string>() {"1","2" }},
       new ComplexHierarchical() { Id= "9",RelationShip="Sister",ImagePath="/diagram/images/people-circle1.png", ReportingPerson=new List<string>() {"1","2" }},
       new ComplexHierarchical() { Id= "10",RelationShip="Nephew",ImagePath="/diagram/images/people-circle4.png", ReportingPerson=new List<string>() {"3","4" }},
       new ComplexHierarchical() { Id= "11",RelationShip="Niece",ImagePath="/diagram/images/people-circle4.png", ReportingPerson=new List<string>() {"5","6" }},
       new ComplexHierarchical() { Id= "12",RelationShip="Niece",ImagePath="/diagram/images/people-circle4.png", ReportingPerson=new List<string>() {"7","8" }},
   };
