This sample visualizes the classifications of species using hierarchical tree layout algorithm. Data Manager support is used to bind data with the diagram.
          This example shows how to generate a diagram from the saved data.
          The dataSourceSettings property can be used to map an
          external data source with the diagram control. The
          id property of dataSourceSettings can be
          used to define a unique field of an external data. The
          parentId property can be used to define the
          relationship between the objects.
        
Injecting Module
          The diagram component’s features are segregated into individual
          feature-wise modules. To generate diagrams from an external data
          source, inject DataBinding module into{" "}
          services. To automatically arrange the objects in a
          hierarchical structure, inject
          DataBinding module into services.
