我是 Graphviz 的新手，我正在尝试绘制以实体为中心的树（我正在使用twopi命令）。
- 如果我把
overlap=true它重叠，即使重叠标签周围有很多空间。 - 如果我放
overlap=false，标签会变得太小。
我怎样才能在不重叠的情况下拥有第一种情况？
完整代码：
digraph g {
graph [ fontname = "Helvetica",
fontsize = 10,
size = "500,500",
splines=true,
overlap=false,
ratio=.5 ];
node [ shape = plaintext,
fontname = "Helvetica" ];
root="owl:Thing";
"owl:Thing" -> "Work";
"Work" -> "WrittenWork";
"Work" -> "Software";
"Work" -> "Website";
"Work" -> "Film";
"owl:Thing" -> "Agent";
"Agent" -> "Organisation";
"Organisation" -> "Non-ProfitOrganisation";
"Organisation" -> "GeopoliticalOrganisation";
"Organisation" -> "SambaSchool";
"Agent" -> "Person";
"Person" -> "Athlete";
"Person" -> "OfficeHolder";
"Person" -> "Astronaut";
"Person" -> "Philosopher";
"Person" -> "Architect";
"owl:Thing" -> "Drug";
"owl:Thing" -> "Place";
"Place" -> "SiteOfSpecialScientificInterest";
"Place" -> "PopulatedPlace";
"PopulatedPlace" -> "Country";
"PopulatedPlace" -> "Continent";
"PopulatedPlace" -> "Atoll";
"Place" -> "ProtectedArea";
"Place" -> "ArchitecturalStructure";
"Place" -> "HistoricPlace";
"Place" -> "NaturalPlace";
"NaturalPlace" -> "Mountain";
"NaturalPlace" -> "Volcano";
"NaturalPlace" -> "MountainRange";
}
谢谢，
