Graphviz将dot文件转为结构图的pdf文件

      cmd，在dos环境下，dot-Tpdf input.dot -o convertoutput.pdf命令，即可将niu.dot转为niu.pdf。我的dot文件是下边这个模样

digraph Tree {
node [shape=box] ;
0 [label="native=no <= 0.5\nentropy = 0.985\nsamples = 14\nvalue = [6, 8]"] ;
1 [label="entropy = 0.0\nsamples = 7\nvalue = [0, 7]"] ;
0 -> 1 [labeldistance=2.5, labelangle=45, headlabel="True"] ;
2 [label="income=high <= 0.5\nentropy = 0.592\nsamples = 7\nvalue = [6, 1]"] ;
0 -> 2 [labeldistance=2.5, labelangle=-45, headlabel="False"] ;
3 [label="entropy = 0.0\nsamples = 6\nvalue = [6, 0]"] ;
2 -> 3 ;
4 [label="entropy = 0.0\nsamples = 1\nvalue = [0, 1]"] ;
2 -> 4 ;
}

digraph Tree {
node [shape=box] ;
0 [label="native=no <= 0.5\nentropy = 0.985\nsamples = 14\nvalue = [6, 8]"] ;
1 [label="entropy = 0.0\nsamples = 7\nvalue = [0, 7]"] ;
0 -> 1 [labeldistance=2.5, labelangle=45, headlabel="True"] ;
2 [label="income=high <= 0.5\nentropy = 0.592\nsamples = 7\nvalue = [6, 1]"] ;
0 -> 2 [labeldistance=2.5, labelangle=-45, headlabel="False"] ;
3 [label="entropy = 0.0\nsamples = 6\nvalue = [6, 0]"] ;
2 -> 3 ;
4 [label="entropy = 0.0\nsamples = 1\nvalue = [0, 1]"] ;
2 -> 4 ;
}
