When you talk about Data Visualization, the first word that comes to your mind is – Tableau. I am guessing that’s why you might be here reading this Tableau tutorial because you have heard about the advantages of Tableau. 

This is my first blog in this Tableau Tutorial blog series which will explain how to get started with Tableau. Hope you will enjoy learning about Tableau with this Tableau Tutorial blog.

 Well you came to the right place. In this Tableau Tutorial, you will be learning the following topics:

  • Importance Of Data Visualization
  • Data Visualization Tools
  • Why Tableau?
  • What Is Tableau?
  • Tableau Product Family
  • Understanding More About Tableau
  • Visualizations
  • Use Case – Datamatics

Let us first start this Tableau tutorial by understanding the concepts behind Data Visualization.

Importance Of Data Visualization

Data Visualization is one of the most important part of data analysis. It has always been important to present the data in an understandable and visually appealing format. Data visualization is one of the skills that Data Scientists have to master in order to communicate better with the end users.

Data is the word here.

Let me first give you an idea of the kind and amount of data that we are dealing with. According to SiliconAngle, there was 2.5 zetabytes of stored data world over in the year 2012 and it is set to hit more than 50 zetabytes mark by the end of 2017. To put things in perspective, this data has largely been produced by websites and cross platform transactions. Add to it the fact that there would be a total of 20 billion “smart” devices connected to the internet by the end of 2020 and the numbers can be baffling!

Data visualization allows data scientists to converse with their end users. The outcome of data analysis is not immediately comprehensible to the people who do not directly deal with data. Data visualization bridges that gap and makes people appreciate the possibility of data analysis.

Let us consider the following example to understand this:

The following image shows the x and y co-ordinates of different points to be plotted on a graph. The numbers look almost the same, don’t they? Maybe the lines will look similar after we plot each set on the graph.

So, now take a look at the image below when we plot these points in our graph:

Graphical Visualization - Tableau Tutorial - Edureka

You see how different they look like when you actually visualize it. It wasn’t possible for us to figure out the nature of each line until we visualized it.

Tableau Tutorial: Introduction To Data Visualization Tools

Here are the top 5 data visualization tools that are being used extensively in BI:

  1. Tableau
  2. Qlikview
  3. Domo
  4. Microsoft power BI
  5. Excel

Let us know a little bit about all of them.

Tableau - Tableau Tutorial - EdurekaTableau:

Basic version of Tableau data visualization tool is free which can perform regular tasks such as:

  •   Sales data analysis
  •   User density monitoring
  •   Consumer segmenting
  •   Tracking budgeting expense
  •   Categorizing and sub-categorizing data

Excel - Tableau Tutorial - EdurekaExcel:

You can actually do some pretty complex things with Excel, from ‘heat maps’ of cells to scatter plots. As an entry-level tool, it can be a good way of quickly exploring data, or creating visualizations for internal use, but the limited default set of colors, lines and styles make it difficult to create graphics that would be usable in a professional publication or website.

MSBI - Tableau Tutorial - EdurekaMicrosoft Power BI:

Microsoft Power BI is a cloud-based business intelligence and analytics service that provides a full overview of your most critical data.

Connecting to all of your data sources, Power BI simplifies data evaluation and sharing with scalable dashboards, interactive reports, embedded visuals and more.

Domo - Tableau Tutorial - EdurekaDomo:

Domo is designed to be available for all business users, regardless of technical expertise, to help them make better business decisions.

Domo recently launched Business Cloud, the world’s first open, self-service platform to run an entire organization. Business Cloud brings together the data, the people and the insights users need to find answers to critical business questions and make faster, better-informed decisions to improve performance.

Qlikview - Tableau Tutorial - EdurekaQlikview:

The QlikView business discovery platform is one of a few visual analytics tools offered by Qlik. QlikView can’t create the same elegant visualizations that the other tools offer, but the software’s dynamic model means that you can quickly analyze your data in multiple dimensions. In addition, QlikView is able to work off of data in memory instead of off your disk, allowing for real-time operational BI environments (like monitoring financial transactions).

QlikView is able to work with a wide variety of data sources, including SAP, Oracle, and other legacy data files like Excel spreadsheets. What’s more, QlikView can combine these disparate data sources into a single visualization or dashboard.

But now the big question is which tool should you go for? Well, I say go with Tableau. Take a look below to know why.

Why Tableau?

Below are some of the pros or features of Tableau which will spellbind you to start using it right away!

Tableau Features:

1. Apt visualizations:

Tableau connects to many different data sources and can visualize larger data sets than Power BI can. Once in Tableau, a dashboard shows the basics of the users’ data. The user can then drill down into data sets by downloading a worksheet. From there, they can apply various visualizations to the data.

In Tableau, you select the data and switch between visualizations on the fly. It’s easier to jump between visualizations in Tableau.

Tableau visualizes data from the start, allowing you to see the significance right away. Tableau differentiates correlations using color, size, labels and shapes, giving you context as you drill down and explore on a granular level.

2. Depth of discovery:

The features of Tableau gives users ways to answer questions as they investigate data visualizations. The solution can show basic trends as predictions, use “what if” queries to adjust data hypothetically, and visualize components of data dynamically for comparisons.

3. Implementation:

Tableau provides a variety of implementation and consulting services. For enterprise-level deployment, there’s a four-step process spanning weeks, and for smaller-scale deployments, there are quick-start options that can complete setup in a matter of hours.

Tableau provides a variety of implementation and consulting services. For enterprise-level deployment, there’s a four-step process:

  • Phase 1 – This phase involves IT planning, architecture consulting, pre-install checkup, server installation and verification, and validation of security configuration.
  • Phase 2 – Phase 2 involves working with data and data migration, including data modeling, data mining, data extraction, data sources and business workflow.
  • Phase 3 – In Phase 3, there’s a two-day classroom training covering Tableau Fundamentals, hands-on advanced coaching, and building and formatting visualizations.
  • Phase 4 – This final phase helps companies expand Tableau usage across their business. It includes implementation workshops where topics such as evaluating action plans and defining measurable outcomes are discussed.

4. Automation functionality:

Tableau is a little more intuitive with creating processes and calculations. For example, when creating calculations in a tabular format, the formula can be typed once, stored as a field and applied to all rows referencing that source. This makes it easier to create and apply recurring processes. Tableau’s flexibility also allows users to create custom formulas that aren’t available in most of the tools.

5. Data source connectors:

Tableau offers hundreds of native connectors to easily pull, cleanse and correlate data from practically any source without having to create custom code.

Tableau extracts large data sets from sources for quick, ad-hoc analysis using two different methods: Live Connection and In-memory. Both adapt to your local database and, based on the size and capacity, sync data quickly by extracting the relevant data to a query. It also has a general Open Database Connectivity (ODBC) connection for any connections that don’t have a native connector provided.

In order to make it more understandable to you, A dimension is used to add more detail to describe your data.

How To Use Tableau?

You just need to follow the below 3-step mantra to use Tableau:

  1. Connect to data
  2. Play around with the UI
  3. Create visualizations

1. Connect to data

The first thing to do in Tableau is to connect to your data. There are mainly two types of connections-

Connecting to your local file or connecting to a server.

Connect To Data - Tableau Tutorial - Edureka

Tableau can connect to any local file or database such as-

  • Excel
  • Text File
  • Access
  • Statistical File, or
  • Other Database file.

Local connection gives the maximum speed of data processing.

Tableau can connect to your data server too. It can connect to almost any type of data server. Below are some of the most popular databases that Tableau can connect:

  • Tableau Server
