# graph-support

#### introduce
The ultimate goal of graph-support is to implement a pure Java implementation of [graphviz](https://gitlab.com/graphviz/graphviz/) .This means that there is no need to install Graphviz on the computer, and there is no need to rely on a V8 javascript engine like [graphviz-java](https://github.com/nidi3/graphviz-java), which is very convenient and efficient to use . 

**builder style api**

```java
// initialize node
Node n_ksh = Node.builder().label("ksh").style(NodeStyle.DASHED).build();
    Node n_System_V = Node.builder().label("System_V").color(Color.RED).build();
    Node n_vsh = Node.builder().label("vsh").fontSize(36).build();
    Node n_Mashey = Node.builder().label("Mashey").style(NodeStyle.FILLED).fillColor(Color.GREEN).build();
    Node n_ksh_POSIX = Node.builder().label("ksh_POSIX").build();
    Node n_Thompson = Node.builder().label("Thompson").build();
    Node n_ks_i = Node.builder().label("ks_i").style(NodeStyle.BOLD).build();
    Node n_Formshell = Node.builder().label("Formshell").build();
    Node n_Bash = Node.builder().label("Bash").build();
    Node n_v9sh = Node.builder().label("v9sh").build();
    Node n_POSIX = Node.builder().label("POSIX").build();
    Node n_rc = Node.builder().label("rc").build();
    Node n_tcsh = Node.builder().label("tcsh").build();
