Klein is a database topologizer. It turns a pair of columns in a database into a directed graph, e.g. senders and recipients of emails, machines in a network, arrival/departure locations on an airline schedule, etc. Output is in Graphviz's DOT format.
Here are some key features of "Klein":
· specify any necessary connection parameters
· read two user-specified columns (currently, must be in the same table; this will be changed soon) and output a Graphviz .DOT file
· specify a minimum edge weight for inclusion -- if your graph is very large and has some heavy edges and many light ones, you can prune out the light ones
