graphviz 2.38.0-4 (arm64 binary) in ubuntu utopic

 Graph drawing addresses the problem of visualizing structural information
 by constructing geometric representations of abstract graphs and networks.
 Automatic generation of graph drawings has important applications in key
 technologies such as database design, software engineering, VLSI and
 network design and visual interfaces in other domains. Situations where
 these tools might be particularly useful include:
 .
   * you would like to restructure a program and first need to understand
     the relationships between its types, procedures, and source files
   * you need to find the bottlenecks in an Internet backbone - not only
     individual links, but their relationships
   * you're debugging a protocol or microarchitecture represented as a
     finite state machine and need to figure out how a certain
     error state arises
   * you would like to browse a database schema, knowledge base, or
     distributed program represented graphically
   * you would like to see an overview of a collection of linked documents
   * you would like to discover patterns and communities of interest in a
     database of telephone calls or e-mail messages
 .
 This package contains the command-line tools.
