Welcome back to week three.

This week we're going to focus on data visualization.

Data and analytics is all about bringing client challenges to life.

We can help clients overcome these challenges by taking data, whether

structured or unstructured, and turning it into usable information and insights.

Visualization is a technique that allows us to consolidate and view data

in an illustrative manner to communicate a message more clearly or create a platform

where we can internalize and further explore our data in a visual format.

Data can be displayed in a variety of formats and effective data visualization

will help us improve our ability to make informed decisions and

judgements from the data we're analyzing.

Many of you may be familiar with some of the basic types of visualization

techniques.

For example, tables, charts, and graphs.

So, how is this different than something we already know?

During this week we will discuss how to enable effective storytelling

trough the correct selection, creation, and presentation of tables and charts.

We're going to start by discussing data visualization basics and

outline basic design principles.

We'll then go into the theory of behind how to enhance the effectiveness of

the message through the use of graphical elements.

There are some general principles that apply across all data

visualization projects.

If you can master these principles you can significantly enhance

the effectiveness of your message.

Following these foundational videos we will go into more detailed charting

demonstration.

Creating graphs and charts of data visualization are mainly used for

one of two purposes, exploration and explanation.

This course will not cover exploration or finding the story in detail.

At a high level,

charts use for exploration support a hypothesis driven approach, and work to

discover something in the data that was not previously known or confirmed.

Instead, during this week we will focus on charts,

with the purpose of explanation or telling the story of the data.

We're going to show you how to build five common graphs that we often use

here at PwC.

Column graphs, 100% stacked charts, combo graphs, heat maps, and gantt charts.

We will review how to select which one is appropriate for a given purpose, and

how to use them most effectively.

Like the previous weeks, we will be using Excel as the platform for

creating these graphs.

It is important to know that there are systems and

graphing platforms available for data visualization

which are much more extensive than Excel, Tableau and R to name a few.

This course will not cover how to use this platforms,

however, they're certainly worth exploring after you've gain understanding of

the foundation of data visualization.

It is important to note the design principles you'll be exploring can be

applied in infinite ways across many different charts, graphs and visuals.

It's up to you to figure out how to best use them.

By the end of this week you will be able to select and

build charts that will effectively tell your story and further internalize data.

We're seeing that data and

analytics today is underpinning every kind of business challenge.

Being able to visualized data in a meaningful way allows you

to present an analysis so that anyone can understand what the information means.

Enjoy the lessons and exercises presented this week.

I'll be back at the end of the week.
