问题描述

我有一个脚本可以将图形打印为 .dot 文件.我想用独特的颜色突出显示所有不同程度的顶点.Graphviz 可以吗?

I have a script which prints a graph as .dot file. I would like to highlight all vertices of different degree with distinctive colors. Is it possible with Graphviz?

所以，我对以下内容感兴趣:

So, I am interested in the following:

For each i-degree vertex use color[i].

作为一种特殊情况，如何用独特的颜色标记树中的所有叶子?:

and as a special case, how to mark all leaves in a tree with a distinctive color? :

For each 1-degree vertex use color_A.

推荐答案

尝试使用 graphviz 实用程序 gvpr 来编写图形脚本.尤其是

Try the graphviz utility gvpr for writing graph scripts. In particular,

gvpr -c 'N[degree==1]{color="red"}'

gvpr -c 'N[degree==1]{color="red"}'

您可以增强它以定义数组(或关联映射)并查找 color[$.degree]

You can enhance this to define an array (or associative map) and look up color[$.degree]
