−
This script generates a demo graph. The graph reflects articles (about [[:Category:Painter|painters]]) and their interrelationships.
+
This example shows a small graph together with its WGL and the resulting GDL.
−
If you click the thumb image you will get the SVG file in which nodes contain clickable links to wiki articles.
+
In GDL,
 +
* a footprint about the generation date is inserted
 +
* colors are translated
 +
* display_edgelabels is set to true by default
 +
* node and edgetypes are 'flattened'.
 +
* egdetypes are mapped to 'classnames'.
 +
* href's are converted

A second example

This example shows a small graph together with its WGL and the resulting GDL. In GDL,

  • a footprint about the generation date is inserted
  • colors are translated
  • display_edgelabels is set to true by default
  • node and edgetypes are 'flattened'.
  • egdetypes are mapped to 'classnames'.
  • href's are converted
with manhattan edges,
top down orientation 		with splines
left to right orientation

{{#wgraph: thumb=50 | svg | png | gdl | node Picasso { } edge Signac Picasso { } node Gauguin { type Painter;Poet } node Henri_Matisse { url Henri_Matisse } node Signac { type Painter scaling 2 bordercolor blue}

edge Gauguin "Henri Matisse" { 

                     type friend;roommate}

edge from Gauguin to Signac { 

                     type friend 
                     label "good friend"}

edge from Signac to Henri_Matisse {} nodetype Poet { color=green shape=ellipse } nodetype Painter { color yellow } edgetype roommate { color gold } edgetype friend { color #ff33aa fontname:HelvO10 } orientation top_to_bottom splines = yes }}

{{#wgraph: thumb=50 | wgl | node Picasso { } edge Signac Picasso { } node Gauguin { type Painter;Poet } node Henri_Matisse { url Henri_Matisse } node Signac { type Painter scaling 2 bordercolor blue}

edge Gauguin "Henri Matisse" { 

                     type friend;roommate}

edge from Gauguin to Signac { 

                     type friend 
                     label "good friend"}
