5 Graph Description Language (GDL) - Absint

info3: "href:#; onMouseOver:foo(1); onMouseOut:foo(0)"
As of aiSee 2.1.96, the URL specification can be omitted:
info3: "onMouseOver:foo(1);onMouseOut:foo(0)"
If aiSee spots a mouse event handler specification in the GDL source of a graph, it automatically
includes a reference to an external JavaScript file when exporting the graph to SVG:
This allows JavaScript functions and global variables to be conveniently specified in the
external JS file rather than in the SVG file itself. Thanks to this approach, you can easily
make changes to your graphs and re-export them to SVG without having to copy & paste
JavaScript code from old SVG files into new ones each time.
• label
Type: string
Default value: empty string
Attribute of: node
Description:
This string is displayed inside a node. If no label is specified the value of the node attribute
title is used.
Note: This string may contain control characters, e. g. “\n” (newline character), that influence
the size of the node. See p. 109 for more details.
• level
This is a synonym for vertical_order.
• loc
Type: { x: y: }
Default value: no default value
Attribute of: node
Description:
This attribute specifies the location of the node, i. e. the x and y coordinates in relation to
the coordinate system of the graph. The origin is in the upper left corner. For example, the
specification loc: { x: 100 y: 200 } places a node at location (100, 200) in
the coordinate system.
The location of nodes are not valid unless locations are specified for all nodes, otherwise
aiSee calculates appropriate x and y coordinates according the layout algorithm chosen.
• margin
Type: int
Default value:
3, if borderwidth (p. 93) > 0
0, if borderwidth = 0
Attribute of: node
