Problem Statement

The air quality index $($AQI$)$ is an index for reporting air quality on a daily basis. It is a measure of

how air pollution affects one's health within a short time period. The purpose of the AQI is to help

people know how the local air quality impacts their health. The pollutants monitored are Sulphur

Dioxide $($SO$2),$ Nitrogen Dioxide $($NO$2),$ Particulate Matter $($PM$10$ and PM$2\mathrm{.}5),$Carbon Monoxide

$($CO$),$ Ozone$($O$3)$ etc.

Central Pollution Control Board is executing a nation$-$wide programme of ambient air quality

monitoring known as National Air Quality Monitoring Programme $($NAMP$)$ and you are part of the

project. As part of the programme, below data has been collected.

Source: This data has been published on Open Government Data platform India by the Ministry of

Environment, Forest and Climate change, and is updated periodically.

You have been tasked to perform an analysis of the data and present the results to the Chairman of

CPCB$.$ With the given context, you need to create a dashboard using TABLEAU. $($Use the concepts

learned in the class$).$

The objectives include

Air$\_$Quality$\_$Analysis

$\_$Data.zip

Demonstrate the VISUALISATION CONTEXT

$1.$ WHO?KNOW YOUR AUDIENCE$($First $2$ questions are answered for you$)$

a$.$ List the primary groups or individuals to whom you$$ll be communicating.

CPCB

b$.$ If you had to narrow that to a single person, who would that be$?$

CPCB CHAIRMAN

c$.$ What does your audience care about?

d$.$ What action does your audience need to take?

e$.$ What is at stake? What is the benefit if the audience acts in the way you want them

to$?$ What are the risks if they don$$t$?$

$2.$ WHAT?

$$ What are you trying to communicate? What questions are you trying to

answer$/$display in your visualizations? Write these as specific questions. You need

to come up with $3$ questions at least, each of which will be answered using one Viz.

$$ Data preparation needed to answer the specific queries must be done.

$3.$ Present the BIG IDEA.

$$ It should: $(1)$ articulate your point of view, $(2)$ convey what$$s at stake, and $(3)$ be a

complete $($and single!$)$ sentence.

$4.$ HOW?

a$.$ Chart $1$: What type of viz did you create? Why did you select the viz that you did?

b$.$ Chart $2$: What type of viz did you create? Why did you select the viz that you did?

c$.$ Chart $3$: What type of viz did you create? Why did you select the viz that you did?

d$.$ For each of the Visualisation, identify at least $3$ Gestalt principles employed.

e$.$ For each of the Visualisation, mention how you strategically used pre$-$attentive

attributes to draw the audience's attention.

$5.$ Create your dashboard

$2.$ Deliverables

Zipped file containing

$1.$ The word doc with answers to question $1$ through $4$ above.

$2.$ The tableau workbook$(.$twbx$)$ with $3$ Sheets$($Each sheet should have $1$ visual$)$ and $1$

Dashboard comprising all three visuals.

$3.$ The source file after preprocessing$($if any$).$

The file name should be the respective group name.

$3.$ Deadline

$$ The strict deadline for submission of the assignment is EoD.

$$ Late submissions won$$t be evaluated.

$4.$ How to submit

$$ This is a group assignment.

$$ Each group consists of up to $3$ members. All members of the group will work on the same

problem statement.

$$ Each group should zip the deliverables and upload in CANVAS in respective locations

under ASSIGNMENT Tab.

$$ Assignment submitted via means other than through CANVAS will not be graded.

$5.$ Evaluation

Sl$.$

No
