  Hi Keith, it will be Python/tree.py in the next release. Until then, here’s the code.

  import xmlrpclib
  import time
  
  # Create an object to represent our server.
  server_url = 'http://127.0.0.1:20738/RPC2'
  server = xmlrpclib.Server(server_url)
  G = server.ubigraph
  
  G.clear()
  
  # Set default edge style
  G.set_edge_style_attribute(0, "oriented", "true")
  G.set_edge_style_attribute(0, "color", "#C5892F")
  # "#DEF33C")
  
  # Default vertex style
  G.set_vertex_style_attribute(0, "shape", "none")
  
  # Vertex style for leaves
  leaf = G.new_vertex_style(0)
  G.set_vertex_style_attribute(leaf, "color", "#80219C")
  # #1768f3
  G.set_vertex_style_attribute(leaf, "shape", "cube")
  G.set_vertex_style_attribute(leaf, "size", "3.0")
  
  # Recursive tree construction
  def subtree(parent,n):
    v = G.new_vertex()
    e = G.new_edge(parent,v)
    G.set_edge_attribute(e, "width", str(1.0 + n))
  
    if (n > 0):
      for j in range(0,2):
        v2 = subtree(v,n-1)
    else:
      G.change_vertex_style(v, leaf)
      time.sleep(0.02)
    return v
  
  # Make a root vertex and build the tree
  root = G.new_vertex()
  x = subtree(root,8)

  G.set_edge_style_attribute(0, “oriented”, “true”)

  does that line control how your tree grows top-down? running your code in my environment (osx 10.4.11) has my tree growing out from the center. i can send a screenshot if you want.

  i don’t see anything in the docs about that style. ( next version, maybe? :] )
