Tableau Dashboard For Data Visualisation Plan Assignment - James Cook University

Assignment Task

Overview

During this assessment you will produce an interactive Tableau Dashboard and an accompanying report detailing the planning of the Tableau Dashboard.

Background

Tableau dashboards are used extensively for data communication and careful design of a dashboard is essential to deliver the dashboard purposes. An effective plan incorporates planning at two levels, the individual visual (worksheet) level and the dashboard level.

Planning for both the visualisation (worksheet) and dashboard levels can be done using the four-stage planning cycle of (1) Domain situation (2) Data/Task abstraction (3) Visual Encoding and (4) Algorithm selection. Planning the worksheets and dashboards is an iterative cycle as the themes of the visualisation choices needs to be coherent to effectively communicate the desired messages. Additionally, the interactivity between visualisations, and between the dashboard and the visualisations, also needs to be coherent, cognitively easy (intuitive) and focused to aid users draw meanings from the data.

Data

For this assignment, you are to produce a Tableau dashboard using the supplied NAPLAN or AirBNB data sets, which is located and described in the Data Sets folder of this assessment. The data sets comprise of multiple data files, any combination of which can be used in your dashboard.

Tasks

This assessment comprises of two tasks:

1. A dashboard visualisation plan
2. A Tableau dashboard implementing the The Tableau Dashboard must contain a Map worksheet plus a minimum of three other worksheets containing charts (visualisations).

The dashboard purpose must relate to the chosen data set, otherwise you have the liberty to choose the dashboard purposes.

A. Dashboard Visualisation Plan: The report

The plan may deviate from the final produced Tableau dashboard. However, the dashboard must be a broad implementation of the proposed plan. You are required to write the plan for university academics or other data scientists (i.e. NOT for target audience of the intended dashboard). Suggested word lengths are provided in parenthesis (brackets).

1. Dashboard The dashboard purpose must include:

• Identification of the target audience (domain) and provide a general description of that audience
• Visualisation, Data and Time assumptions concerning the target audience
• The intent(s) of the dashboard

2. Dashboard Layout. Describe (and/or provide wireframe), discuss and justify the layout of the dashboard including

1. Worksheets (including the geographic map)
2. Filters
3. Annotations
4. Navigation elements
5. Highlights
6. Parameters

3. Dashboard Visualisation Themes: Describe and justify the Marker, Channel and Aesthetics themes used for the dashboard and across worksheets 

4. Worksheets. For each Worksheet, including the geographic map, detail/tabulate:

a. Identification of

• Intent
• Visualisation type and
• Task abstractions of the worksheet

b. Discussion of alignment between the:

• Worksheet intent and the dashboard intent/desired response
• Worksheet Visualisation type and the Audience assumptions
• Worksheet task abstractions (including any interactivity) and the worksheet and dashboard intent/desired response

5. Dashboard Data – this section is to be a table(s) comprising of: (100 – 300)

• Identification and summarisation of all required original variables
• Identification, description and summarisation of any calculated parameters or variables derived from the original variables
• Identification of where the variables/derived values are used in the dashboard (i.e. worksheet number, visualisation, annotation, filter number, , tooltip, etc)

6. Dashboard Interactivity. 

a. List or tabulate the dashboard interactivity elements including any:

• Filters
• Highlights
• Action filters
• Navigation buttons
• Annotations
• Tooltips

b. Discuss the alignment of these interactive elements with the

• Audience assumptions
• Dashboard Intent/Desired response

B. Tableau Dashboard

You must use one of the provided datasets and use Tableau to implement the project in Assessment 4. You are to implement an interactive Tableau dashboard that uses at least four (4) Tableau worksheets that contain charts (visualisation) – and one of the worksheets must be an interactive geographic map. The interactive map must interact with at least one other Tableau worksheet contain a chart (visualisation). For example, selecting a data marker on the map filters the data presented on a bar chart.

The maximum size of the dashboard is 1000 by 800 pixels, the default desktop browser size.

The dashboard is an implementation of the visualisation plan and the dashboard need to demonstrate the following:

1. Interactivity . You should demonstrate use Tableau interactive elements in both the tableau dashboard and your tableau Tableau interactivity elements include:

• Filters
• Highlighting
• Action filters
• Annotations
• Tooltips
• Data Drill Down/Up
• Paging or Cascading i.e., interactivity between worksheets

2. Visualise and calculate complex data . Demonstrate visualisation of complex data in at least two worksheets and on the dashboard panel. Complex data is data that is not immediately available from the raw data sources. For example, you may create calculated fields, parameters or analytics to derive information, new variables, annotations, frequencies, trend lines, or You should demonstrate:

• Calculation of new fields and parameters
• Use of Tableau analytics
• Application of complex data in worksheets using a variety of visualisation types (charts)
• Integration of calculated fields/parameters with filter, chart, marker, channel or annotation controls

3. Application of design principles . Effective use of markers, channels, charts, controls and effective use of layout (space), both on a worksheet and dashboard You should demonstrate

• Effective use of dashboard space . You may use all four worksheets on the dashboard panel – or alternatively one (or more) worksheets can be used within tooltips in the
• Coherent use of a visualisation theme (i.e., channels and marker choices) on a dashboard and worksheet levels
• Application of visualisation choices for expressiveness and effectiveness
• Application of visualisation principles for aesthetics
