These Are Five Common Types of Data Visualizations (And When They Should Be Used).

This section will introduce you to some types of data visualization. You can also refer to our comprehensive guide to learn more about data visualization and how to use them.

Scatterplots

Scatterplots, or scatter graphs, visualize the relationship between two variables. The x-axis shows one variable, while the y-axis shows the other. Each data point is represented as a single “dot” on the graph. This creates a scatter effect, hence the name.

When there is no temporal component, scatterplots work best for large datasets. A scatterplot can be used to visualize relationships between height and weight or the value of a diamond in terms of its carats and its monetary value. Remember that scatterplots only describe the relationship between two variables. They don’t infer any cause-and-effect relationship.

Bar Charts

Bar charts can be used to compare categorical data with discrete values. Categorical data is data that doesn’t have a numeric value. It is often used to identify certain traits and characteristics. Categorical data can be used to describe things such as education level (e.g. High school, post-graduation, or undergrad) as well as age (e.g. Under 30, 40, 50, 50, 50, and 50 years old. Discrete values can only be taken on certain values. There are no “half measures” and “gray areas”. A discrete variable could be the number or attendees at an event, or the sales in a given time period. (Think about it: You can’t make half a sale, or have half the event attendees.)

Pie Charts

Pie charts can be used to visualize categorical data in the same way as bar charts. Pie charts, on the other hand, can be used to visualize a single variable, broken down into percentages and proportions. Bar charts, however, represent many types of data. A pie chart is basically a circle divided into “slices”, with each slice representing the percentage of the total. The size of each slice is proportional the amount it contributes to the “pie.”

Network Graphs

Some data are too complex to be summarized in a pie or bar chart. There are many data visualizations available for complex datasets. One example is network graphs. Network graphs are a way to see how elements or entities in a network interact with one another. Each element is represented by a node. These nodes can be connected via lines to other related nodes.

Maps of the World

Geo maps can be used to visualize data distribution in relation to a geographical area. A color-coded map could be used to show the distribution of natural oil reserves around the globe or how states voted in an election. Maps can be used to communicate all types of location-related data.
