Description

Data visualizations are a graphical representation of data that tell a story and can be used to identify trends, patterns, and relationships. Visualizations can be static, animated, or interactive. 

  • Static visualizations provide users with a single view of data
  • Animated visualizations incorporate motion to convey information to users
  • Interactive visualizations allow users to interact with and customize visualizations.

Common types of visualizations include:

Bar Charts Pie Charts Line Charts
Compare data across categories Show proportions of a whole Show trends over time

Bar chart comparing body mass of penguins by species (Adelie, Chinstrap, and Gentoo) and gender (male and female).

Tools

In order to visualize data, you will need access to visualization software. There are two types of visualization software: Graphical User Interface (GUI) software and code-based software.

Graphical User Interface (GUI)

Excel is a popular spreadsheet editor with a variety of graph and chart options for visualizing data. Excel is FREE for all University of Mississippi faculty, staff, and students as part of the campus-wide Microsoft Office 365 license.

Tableau is a tool with a simple to use "drag-and-drop" interface that allows users to create interactive visualizations and dashboards from a variety of data sources.  Tableau Public is FREE to use.

Power BI (Business Intelligence) is a collection of software services, apps, and connectors that work together to turn raw data into static or interactive visualizations.  Power BI is s FREE for all University of Mississippi faculty, staff, and students as part of the campus-wide Microsoft Office 365 license.

Code Based

R is a FREE software environment for statistical computing and graphics. R packages such as ggplot2 are used for data visualization.

Python is a free general purpose programming language. Python libraries such as MatPlotLib and Seaborn are used for creating static, animated, and interactive visualizations.

Shiny is a free package that can be used to create interactive data visualizations in either R or Python. 

SAS is a computer programming language that can be used to create data visualizations. SAS OnDemand is free for academics and offers both programming and point-and-click interfaces.

Data Visualization Resources

The following are curated lists of datasets for visualization. Since any dataset can be visualized, be sure to also check the Datasets section of this guide's "Resources" page.
