Here are some sample SourceGraph analysis reports. Please note that several "code smells" (such as a fair number of inaccessible entities) have been left in SourceGraph and the others for illustrative purposes.
SourceGraph itself: SourceGraph report
Graphalyze: Graphalyze report
graphviz: graphviz report This library has modules with large data structures (Attribute has 145 constructors) and many data types with instances of at least two different classes.
haskell-updater: haskell-updater report This is a smaller program which makes it easier to fully see the types of analysis SourceGraph provides.
