gvmap.sh(1)


NAME

   gvmap.sh - pipeline for running gvmap

SYNOPSIS

   gvmap.sh [-vV?]  [ options ] [ -o outfile ] [ files ]

DESCRIPTION

   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.

OPTIONS

   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.

   -v     Set verbose mode.

   -V     Print version information and exit.

   -?     Print usage information and exit.

EXAMPLES

   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

Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.



Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.



Free Books


The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.



Education


Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
