Employing Color Effectively
06:32

Before we can create great data visualizations, it is imperative to be familiar with the underlying data. Knowing the data type will allow us to choose the best way to display the data.

Preview 07:39

We will show some examples of categorical data, so that we can begin to understand how it is used and where it is likely to be found. After gaining an understanding of these examples, we can then begin applying our knowledge.

Categorical Data
06:26

To visualize time series data, we need to first be able to identify it within a dataset. From there, it is important to know what level of granularity is required by the end user, so that we can create the appropriate visualization.

Time Series Data
08:49

In this video we will look at point data and learn how to recognize, understand, and ultimately display it effectively.

Point (X-Y) Data

We'll cover the background, structure and use of network data in this video. Once the basics of data structure have been covered, we'll learn how to create compelling visualizations.
Network Data
07:33

This video will focus on the rise of unstructured data. We'll learn many types and sources of this type of data, and then explore how it can be effectively visualized.

Unstructured Data
06:16

Line charts are one of the most commonly used chart types, and are especially useful for display of time series data. Yet there are many opportunities to turn a basic line chart into a more effective visualization.

Preview 09:05

Bar charts are perhaps the most frequently encountered chart type, but are often ineffective at telling a story. We will learn some simple steps to make bar charts both more effective and visually attractive.

Bar Charts
06:43

Scatterplots are most commonly used to show relationships between data pairs using an x-y (and sometimes z) set of axes. Using this approach, we can compare numeric data tied to categorical variables such as stores, departments, countries, and so on, and see the relationship between them.

Scatter Plots
07:21

A distribution plot can be defined as any sort of chart that maps data points along a value axis. In many cases, this will be a single variable with many values accrued over time, plotted to understand the overall pattern.
Distribution Plots
06:29

A dot plot chart should not be confused with statistical plots that have often used the same name. Data visualization dot plots are charts that can often replace bar charts in showing multiple comparative data points on a single axis.
