graphviz 绘图太宽

我正在做练习，在 jupyter 笔记本中使用 graphviz 创建决策树。然而，决策树过于宽泛。这是代码：

from sklearn.tree import export_graphviz
export_graphviz(tree, out_file="tree.dot", class_names=["malignant", "benign"], 
                feature_names=cancer.feature_names, impurity=False, filled=True)
with open("tree.dot") as f:
    dot_graph = f.read()
display(graphviz.Source(dot_graph))

and I get this:

我必须滚动才能看到决策树的左侧。我可以把宽度变小吗？如何？

如果节点树分布广泛，可以尝试

• 为长标签添加换行符（node1 [label="line\nbreak"])
• 全局减少节点宽度和边距（node [width=0.1 margin=0])
• 减少图行中节点之间的距离（graph [nodesep=0.1] https://graphviz.org/docs/attrs/nodesep/)
• 减小图形大小（graph [size="3,3"] https://graphviz.org/docs/attrs/size/)

Or you can put all the nodes in a column with rankdir=LR; edge[constraint=false], as in example below.

Script:

digraph {
    graph [rankdir=LR ranksep=1]
    
    node[shape=box width=3]
    edge[constraint=false]
    
    A -> {B C}
    B -> {D E}
    C -> F
    D -> {G H}
    E -> I
    F -> {J T}
    G -> {K L}
    H -> {M N}
    J -> {O P}
}
