Intro to some diagram auto-generation tools. For more info and sample files, head over to http://www.mbarsinai.com/blog/2014/01/12/draw-more-work-less/.

1. Draw More, Work Less
Computer Generated Diagrams
IQSS Tech talk
2014-01-09
Michael Bar-Sinai

2. Today:
Why and when computer-generated diagrams make sense?
GraphViz
PlantUML (and, also, UML)
Summary

3. Why Let a Computer Draw
Work on semantic level
“From A to B”
Play with parameters (layouts, skins)
A
B
Not that strange (HTML, LaTeX)
A
B
A
B
Play well with CVSs (git/svn/...)
Easy updates
Inspiration for DSLs/APIs

4. GraphViz
http://www.graphviz.org
“drawing graphs since 1988”
Open source, available to most platforms
Mainly Command-line, some GUIs exist

58. …Summing Up
Sometimes its better to concentrate on the structure, and let the
computer do the layout
There are free, capable tools for diagraming
Both GraphViz and PlantUML have numerous features not
covered in this talk

59. Draw More, Work Less
Computer Generated Diagrams
