Problem:
get a overall picture of how ego-networks evolve is a common challenging task.
Existing techniques: inspect the evolution patterns of ego-networks one after another.
Purpose:
how analysts can gain insights into the overall evolution patterns of ego-networks by interactively creating different spatial layouts.
Introduction:
1. What is ego-network and ego-network analysis?
The analysis of individuals in a network context is referred to as egocentric network analysis or ego-network analysis. An ego-network consists of a focal node, the nodes within its one-step neighborhood and all the edges among these node
2. the content in a spatial layout
each dot represents a dynamic ego-network, clusters of dots indicate similar evolution patterns./ outlying dots exhibit uncommon evolution pattterns.
3. interpretability and interactivity.
This technique is developed with interpretability and interactivity in mind
Related work:
1. ego-network visualization
2. dynamic network visualization
3. techniques for creating spatial layouts for sensemaking
Methodology:
1. the visual function of spatial layouts.
create spatial layouts, which provide overviews of the evolution patterns. and each dot in spatial layouts presents a dynamic ego-network.
2. data transformation pipeline: adjust the spatial layouts and convert dynamic ego-networks into event sequences.
