Как использовать ShemaSpyGui для просмотра схемы базы данных

Я установил Postgre сегодня и хочу посмотреть базу данных Шема.

Я решил использовать schemaSpy и скачать его, а также schemaSpyGui

и тогда я вижу:

This is the command (password not displayed!) SchemaSpyGUI has generated: java -jar "D:\free\schemaSpy_5.0.0.jar" -dp "D:\free\postgresql-9.1-903.jdbc4.jar" -t pgsql -db marc_db -host localhost -port 5432 -u marc -connprops "D:\free\schemaSpyGUI20090302\properties\pgsql.properties" -o "D:\free\schemaSpyGUI20090302\marc_marc_db_"  Failed to query Graphviz version information with: dot -V java.io.IOException: Cannot run program "dot": CreateProcess error=2, The system cannot find the file specified Using database properties: [D:\free\schemaSpy_5.0.0.jar]/net/sourceforge/schemaspy/dbTypes/pgsql.properties Gathering schema details...  No tables or views were found in schema 'marc'. The schema does not exist in the database. Make sure that you specify a valid schema with the -s option and that the user specified (marc) can read from the schema. Note that schema names are usually case sensitive.  3 schemas exist in this database. Some of these "schemas" may be users or system schemas.  information_schema pg_catalog public  These schemas contain tables/views that user 'marc' can see:  information_schema pg_catalE=2og publicI=2 

Я установил Graphviz2.38

А если из cmd я наберу

C:\Program Files (x86)\Graphviz2.38\bin>dot -V dot - graphviz version 2.38.0 (20140413.2041) 

Пожалуйста помоги.

Обновить

после консультаций в комментариях я добавил path\to\Graphviz2.38\binк Pathпеременному окружению, и теперь я вижу следующее:
