Abstract – Data Visualization is the combination of art
and science. It is seen as a branch ofdescriptivestatistics. Data
visualization is a very new and promising field in software
engineering. It is a graphical representation of the data that
best conveys the complicated ideas clearly, precisely, and
efficiently. Effective visualization helps users to analyze and
reason about the data and evidence. It makes tedious data
more accessible, understandable and usable.
One of the main goals of data visualization is to give support
in making quicker decision through appropriately designed
graphically represented information. Sophistically-designed
data visualization systems can greatlyassistuserswithproper
reasoning and decision making. Usually, visually presented
data is easier to understand. This project’s main objective is
to provide a plug-in software for data visualization, which is
developed using plug-in based architecture and will be
adaptable for future changes and updates. These plugins will
Allow user to process on different types of files (excel, html, txt,
csv etc.)
Key words: Data Visualization, Plug-in architecture, Spring
boot.
1. INTRODUCTION
In today’s world it is very important and hard to interpret
the huge chunks of data in the industry. Reading Data in the
raw form is very tedious. So there has to be a better way to
read this data. This Data visualization tool will help to read
such data in better way understanding.
Visualization can be considered as an excellent medium to
analyze and share information.[1] The objective of this
project is to create an easy and reliable system for Data
Visualization, provide a plug-in architecture softwarewhich
will be adaptable for future changes and updates, allow user
to process on different types of files (excel, html, csv etc.),
provide rich, interactive visuals, show the story of user’s
data and make it easy to share insights, to give single-output
file to download.
Data visualization also helps in detecting problems
perceiving trends and outliers and also point out absorbing
in a large dataset [6].
2. LITERATURE REVIEW
Datawrapper : It is a web-based visualization tool which is
used to create simple charts and maps for web articles. It
allows user to insert xml, csv , xls files and provides multiple
charts for visualization.[8]
Tableau Software: - Tableau is a commercial tool used for
data exploration; it uses interactive visual dashboards to
represent data and facilitate the exploratory data analysis
process.[7] The user can gain knowledge with their data, by
creating charts, graphs, maps and many other graphics.
RAW :It is a web-based tool that allows user to simply paste
the data and visualize it in graphs. The Raw is based on the
D3.js library, which makes the user to easily accessible, so
that the non-programmers can also visualize it .[9]
3. SYSTEM ARCHITECTURE AND IMPLEMENTATION
To build plug in based application it is requiredtohaveloose
coupling between classes. Loose coupling can be achieved
using interface. [5] The goal of the plugin is to read the data
from different file formats. To achieve this, Reader Interface
is created which has an abstract method call as Read().
Purpose of read method is to read data from file.
Each plugin has to implement this Read() to read data from
file and create the json string out ofit,nowwhoever wants to
build the plugin (jar) to read different file formatwill haveto
implement this reader interface and implement its read
method. This method will now hold the logic toreadthedata
from the corresponding file format Plugin will also have a
metadata file (txt) file. Which will indicatewhichtypeofdata
it is able to read and which class is implementing the reader
interface. Once plugin is ready it can be added into the
application.
Multiple plugins are available in the application so in order
to maintain loose coupling between clients and all these
different plugins Factory design pattern is used. When
client/user uploads a file on to the application this Factory
pattern identifies the file type and calls corresponding
plugin.
The output of this architecture is a JSON file which will be
hosted as webservice. Different visualization patterns are
presented to user on User Interface. By selecting those, user
can visualize corresponding data and also can generate
report.
Framework : Spring boot
IDE : Java Eclipse

How to create new plugin for the system
Plugin is nothing but a jar file. In this system each plugin
represents input files of different formats and responsible
for extraction of same. This plugin (Jar file) should contain a
class which has to implement Read method from Reader
Interface. This class will hold the logic for extraction of data.
For example, Excel plugin
will have a class called Excel Reader which implements
Reader Interface and hold the logic for extraction of excel
data.
Plugin should also has a metadata (text file) file which
indicates type of data it is able to read and which class is
implementing the reader interface. For example, Excel-
plugin will contain following information:
file Type=xls, xlsx
class=com.formatter.service.reader.Excel Reader
To add new plugin to the system simply add executable jar
file in the resources.
System Workflow
 Insertion of file.(fig 2)
 Through the controller file directed to Reader
Factory.
 Reader Factory identifies file type and calls
corresponding plugin by checking itstypewith type
mentioned in metadata file of respective plugin.
 Plugin extracts the data from respective file and
architecture converts it to JSON.
 Now webservice hosts the JSON file which has a
data extracted from users input file. Visualization
patterns gets the data by hitting webservice and
visualize it.
 System allows user to add description for
visualization.(fig 3)
 Also provides various visualization patterns, (fig 4)
which are editable and allows to download in
various formats (jpeg, png, pdf, etc.)

4. SCOPE
As the world turns out to be progressively interconnected
and associated, chances to create an incentive through data
visualization will only increase. The Internet of Things will
profoundly affect the job that data visualization can play in
associations and society, improving our capacity to see how
people and machines collaborate with one another and
nature. Application of evolving cognitive frameworks, like
Network and Complexity Theories, will help usbetter reflect
dynamic and intricate structural dependencies. Also,

advances in multidimensional visualization will allow us to
more viably blend and explore spatiotemporal conditions.
The definition of data visualization explains the importance
of the data by placing the data in terms of visual context [4].
It enables decision makers to see analytics presented
visually, so they can learn difficult concepts or identify new
patterns. With intelligent visualization, you can also drill
down into charts and graphs for more detail, interactively
changing what data you see and how it’s processed.
While we’ll always wax poetically about data visualization
there are practical, real-life applicationsthatareundeniable.
And, since visualization is so prolific, it’s also oneofthemost
useful professional skills to develop. The better you can
convey your points visually, whether in a dashboard or a
slide deck, the better you can leverage that information.
5. CONCLUSION
A plug-in based application for Data Visualizationisa system
which extracts the information from the files provided by
user and allows user to visualize it in various attractive
patterns. The system is flexible enough to accept different
input file formats as per the plug-ins added onto the system.
The great thing about system is that it doesn't require any
technical or any kind of programming skills to operate. By
using this system user can easily visualizeandcreatereports
to share with teams. Effective visualization helps users to
analyze complex data efficiently.
A plug-in based application for Data Visualization is a data
visualization solution that enables users to import data and
generate powerful visuals that are easy to understand and
derive insights from.
