Synopsis Tree layout.

Function Figure tree(Figure root, Figures children, FProperty props...)

Description tree takes a list of nodes and a list of edges and draws a tree.

The orientation property can be used to set the drawing direction, hgap and vgap can be used to set the gaps.

Examples

t1 = tree(box(fillColor("green")),
          [ box(fillColor("red")),
     	    box(fillColor("blue"))
     	  ],
          std(size(50)), std(gap(20))
    	);
render(t1);

The standard way of drawing trees is in manhattan-style: all connection between tree nodes are horizontal or vertical. This style is controlled by the manhattan property:

t2 = tree(box(fillColor("green")),
          [ box(fillColor("red")),
     	    box(fillColor("blue"))
     	  ],
          std(size(50)), std(gap(20)), manhattan(false)
    	);
render(t2);

t3 = tree(ellipse(size(30), fillColor("green")),
          [ tree(ellipse(size(45), fillColor("red")),
     	         [ ellipse(size(60), fillColor("blue")),
     	           ellipse(size(75), fillColor("purple"))
                 ]),
            tree(ellipse(size(90), fillColor("lightblue")),
                 [ box(size(30), fillColor("orange")),
     	           box(size(30), fillColor("brown")),
     	           box(size(30), fillColor("grey")),
     	           ellipse(size(30), fillColor("white"))
                 ]),
            box(size(30), fillColor("black"))
     	  ],
          std(gap(30)));
render(t3);
