      Description copied from interface: LinkStrategy
      Draw node/path connections
      Specified by:
      drawNodeLink in interface LinkStrategy<T>
      Parameters:
      maxDimensionInLine - max dimension in line; if left-to-right or right-to-left, it is width; if top-to-bottom or bottom-to-top, it is height
      parent - parent node
      parentPoint - parent node position
      parentW - parent node width
      parentH - parent node height
      child - child node
      childPoint - child node position
      childW - child node width
      childH - child node height
      nodeLineGap - node connections gap
      vgap - vertical gap: distance between parent and child
      hgap - horizontal gap: distance between child and child (same level/row)
      Returns:
      Node/Path connections; these nodes may be lines and arrows; (The returned nodes should have both layoutX and layoutY already set.)
