Graphs are defined by the <graphgear></graphgear>
tags. The body contains the nodes and edges as explained below. The opening tag can contain optional comma separated parameters.
Complete Example:
<graphgear width=500,height=300,label="My first Graph"> node1 [label="My first node", fillcolor="lightblue"] node2 [label="My second node"] node1 -> node2 [label="An edge from node1 to node2", fontcolor="red"] </graphgear>
The following parameters are supported:
Parameter | Value | Default | Description |
---|---|---|---|
label | any text | A title for the graph | |
width | a number | 725 | The width of the graph in pixels |
height | a number | 400 | The height of the graph in pixels |
bgcolor | a color | ffffff (white) | The background color of the whole canvas |
linecolor | a color | cccccc (grey) | The color of the edge lines |
mode | undirected or directed | undirected | Have the edges of the graph a direction? |
viewmode | explore or display | explore | In explore mode only the first node and it's children is shown initially, in display mode all nodes are shown. The latter is very CPU intensive |
A node is defined by its name, optionally followed by a parameter list in square brackets.

url | a link | Clicking the label will open the given page, can be external or a wiki page | |
image | a image | The image will be shown inside the node bubble, can be external or internal | |
shape | circle or box | circle | The shape of the node. Only circles and squares are supported. A few more graphviz shapes will be recognized as box |
An edge is defined by giving two node names separated by a ->
, optionally followed by a parameter list in square brackets.
Example:
node1 -> node2 [label="An edge from node1 to node2", fontcolor="red"]
Only the following graphviz parameters are supported:
Parameter | Value | Default | Description |
---|---|---|---|
label | any text | A label, describing the edge | |
