gvmap.sh − pipeline for running gvmap
gvmap.sh [−vV?] [ options ] [ −o outfile ] [ files ]
gvmap.sh takes as input a graph in DOT format, performs a layout, runs the output through gvmap and renders the output. At some point, it is hoped to integrate all of these tasks into gvmap.
The following options are supported:
|
−a k |
The integer k specifies the average number of artificial points added along the bounding box of the labels. Such artificial points are added to avoid a country boundary cutting through the boundary box of the labels. Computing time is proportional to k; hence, for large graphs, a small value of k is suggested. If k = -1, a suitable value of k is automatically selected based on the graph size. By default k = -1. |
−K layout
specifies which program should be use for the initial layout. By default, sfdp is run. Also by default, the layout is passed the flag -Goverlap=prism. This can be overridden using a -g flag.
−T format
specifies the final output format. This works the same way as the -T flag for any Graphviz layout program.
−N attr=val
specifies the setting of a default node attribute during the rendering phase. This works the same way as the -N flag for any Graphviz layout program.
−G attr=val
specifies the setting of a graph attribute during the rendering phase. This works the same way as the -G flag for any Graphviz layout program.
−E attr=val
specifies the setting of a default edge attribute during the rendering phase. This works the same way as the -E flag for any Graphviz layout program.
−n attr=val
specifies the setting of a default node attribute during the layout phase. This works the same way as the -N flag for any Graphviz layout program.
−g attr=val
specifies the setting of a graph attribute during the layout phase. This works the same way as the -G flag for any Graphviz layout program.
−e attr=val
specifies the setting of a default edge attribute during the layout phase. This works the same way as the -E flag for any Graphviz layout program.
−A flag
specifies a flag to be passed to gvmap. For example, gvmap.sh -Ae -As3 causes gvmap -e -s3 to be run.

The following invocation creates a map with edges in semi-transparent light gray and nodes laid out using sfdp:
gvmap.sh -Ae -Ecolor=#55555522 -Tpng foo.gv > foo.png
It is equivalent to running the pipeline
sfdp -Goverlap=prism foo.gv | gvmap -e | neato -n2 -Ecolor=#55555522 -Tpng > foo.png
