Aim of the ResearchThe aim of the research is to significantly
improve the analysis of grouped network data using Euler diagrams with graphs by automated visualization (Software).
Example: Facebook is a grouped network, which has millions of users. It can be analyzed using the automated tool which will be developed by us.
IntroductionEuler diagrams are an attractive information
visualization tool which represents relationships between the sets (categories).
Figure: Relationship between the Universities
Introduction (Contd.)Graphs (often termed as network diagrams)
represents the relationship between the data items (people).
Figure: Relationship between the lecturers collaborating with the different University lecturers.
Introduction (Contd.)Euler diagrams + graphs will represent the
relationship between the sets (categories) and the data items (people).

Introduction (contd.)Two important methods in
developing Euler diagrams and Graphs in combination are:
1. Euler drawing method 2. Graph drawing method
>> Our goal is to combine both the methods successfully.
Euler Drawing MethodThe circle based drawing method
for producing Euler diagram was recently devised by Stapleton et al. [1].
The three different colors are described as different zones in the abstract description.
Figure: Euler diagram generated
Euler Drawing Method (contd.)
The main objectives of this method are
To automatically draw an Euler diagram using only circles to represent any data set.
Efficient layout.
Graph Drawing MethodOne of the old and traditional
graph drawing method is Force-Directed Layouts method [2].
The force-directed algorithm is based on the physical model of attraction and repulsion.
Figure: Left handed diagram has edge-crossings in graph and right handed diagram has avoided edge-crossings in graph.
Graph Drawing Method (contd.)
The main objectives of this method are:
To layout the graph optimally.Avoid edge-crossings.
Combining both drawing Methods
A relatively new method combining both Euler drawing method and graph drawing method will be developed which will have benefits and impacts of Euler diagrams and graphs.
Figure: Euler diagram and graph in combination
Combining both drawing Methods (contd.)The main objectives of this method are:Develop novel layout method for drawing
graphs and Euler diagrams in combination.
Develop proof-of-concept open source software.
Efficient layout.
Point1: This method will be open to wide range of applications and reason other issues.
