Uncertain Graph Layout Interface
(or just UGLI)

UGLI is a prototype (which will hopefully grow into a tool) which can be used to visualize mulit-modal, multi-relational networks with uncertainty attached to the attributes of nodes and edges. If that didn't make a lot of sense, check out the paper! Here's the abstract:
Abstract: One problem with visualization is that it can be misrepresentative of the actual data because it is an absolute representation when uncertainty often exists in the data. While various techniques and tools exist for visualizing uncertainty in scientific visualizations, these do not exist for visualizing information such as graph/network data. With the recent prevalence in data which can be represented as a graph (e.g. social networks), graphs are no longer simple, bi-modal datasets with only nodes and edges. Instead, we are often tasked with working with multi-modal graphs where we have multiple types of nodes and edges where each node/edge can have many--perhaps hundreds--of attributes, and these attributes often have some uncertainty attached to them. Moreover, it is often useful to compare multiple graphs of this type as well as the ego networks of nodes in these graphs. In this paper we present various techniques and a prototype tool that can be used to visualize multi-modal graph data with uncertainty attached to each attribute and compare multiple such graphs with one another.
