JVM dot graph file output
DotDump aims to be a very simple dot graph file format output for the JVM.
I found myself writing different hacky dot file dumpers for different projects, so I decided that I’d write a fairly decent one once and for all.
This library 100% java without external dependencies (other than junit) is thread safe.
This is not a graph library, it just writes your graph into dot format.
You can find more info about the dot format at Graphviz web
A simple music chart:
import com.github.lant.dotdump.*;import java.io.File;import java.io.IOException;class Example {public static void main(String ...args) throws IOException {Dot musicGraph = new Dot(GraphType.DIGRAPH, "Some metal bands");musicGraph.withComment("Some metal bands to draw a graph");GraphNode maiden = new GraphNode("iron-maiden").withText("Iron Maiden").withShape(NodeShapes.box);GraphNode sabbath = new GraphNode("b-sabbath").withText("Black Sabbath").withShape(NodeShapes.circle);GraphNode acdc = new GraphNode("acdc").withText("AC-DC").withShape(NodeShapes.diamond);GraphNode mayhem = new GraphNode("mayhem").withText("Mayhem").withShape(NodeShapes.ellipse);GraphNode venom = new GraphNode("venom").withText("Venom").withShape(NodeShapes.house);GraphNode nasum = new GraphNode("nasum").withText("Nasum").withShape(NodeShapes.lpromoter);GraphNode slayer = new GraphNode("slayer").withText("Slayer").withShape(NodeShapes.box3d);musicGraph.withNode(maiden);musicGraph.withNode(sabbath);musicGraph.withNode(acdc);musicGraph.withNode(mayhem);musicGraph.withNode(venom);musicGraph.withNode(nasum);musicGraph.withNode(slayer);musicGraph.withRelation(new NodeRelation(acdc, maiden).withLabel("Influenced"));musicGraph.withRelation(new NodeRelation(sabbath, maiden).withLabel("Influenced"));musicGraph.withRelation(new NodeRelation(slayer, venom).withLabel("Influenced"));musicGraph.withRelation(new NodeRelation(venom, mayhem).withLabel("Influenced"));musicGraph.withRelation(new NodeRelation(sabbath, slayer).withLabel("Influenced"));musicGraph.withRelation(new NodeRelation(slayer, nasum).withLabel("Influenced"));musicGraph.writeToFile(new File("music.dot"));}}
That will generate this dot file:
DIGRAPH "Some metal bands" {# Some metal bands to draw a graph"iron-maiden" [label="Iron Maiden", shape=box];"b-sabbath" [label="Black Sabbath", shape=circle];"acdc" [label="AC-DC", shape=diamond];"mayhem" [label="Mayhem", shape=ellipse];"venom" [label="Venom", shape=house];"nasum" [label="Nasum", shape=lpromoter];"slayer" [label="Slayer", shape=box3d];"acdc" -> "iron-maiden"[label="Influenced"];"b-sabbath" -> "iron-maiden"[label="Influenced"];"slayer" -> "venom"[label="Influenced"];"venom" -> "mayhem"[label="Influenced"];"b-sabbath" -> "slayer"[label="Influenced"];"slayer" -> "nasum"[label="Influenced"];}
