Edge CSVs

An Edge CSV is a list of links, for which each link represents some relationship between two individuals. These links could represent a report of high-risk sexual contact. The file extension must be ".csv". The contents of an Edge CSV should look something like this:

source,target,length
A,B,1
A,C,2
B,C,1
A,D,.5

Each row represents an edge in the network. The source and target columns represent the individuals (or nodes). Note that these column headers are spelled using all-lower case. These columns are mandatory: a network cannot be built without them. Any other columns are allowed.
