SQL Graphviz is a small python script that generates a Graphviz visualization of a SQL schema dump.
SQL Graphviz relies on pyparsing to grok the schema dump. Ubuntu users should install using:
$ sudo apt-get install python-pyparsing
while CheeseShop frequenters should install with pip:
$ sudo pip install pyparsing
Using PostgreSQL, for example, to generate as a PNG file:
$ pg_dump --schema-only dbname | python sql_graphviz.py | dot -Tpng > graph.png
The program will accept a named file, or if omitted as above, will take from stdin. Output to SVG:
$ pg_dump --schema-only dbname > dump.sql
$ python sql_graphviz.py dump.sql > graph.dot
$ dot -Tsvg graph.dot > graph.svg
