Data visualizations include simple graphs like bar and pie charts, scatter plots, and line graphs, but they can also be more complicated, like network visualizations or 3D models. This guide will walk you through the process of deciding if a data visualization project is a good choice for your research.

For any project, but especially data visualization which requires technical skills, it is important to consider how long each step will take. You may be learning a new software platform, organizing and reformatting your data, creating summary statistics, and more. Factor this into your project timeline -- how long do you have to complete this project? A month, a semester, a year? Knowing this will help you choose an appropriate tool and visualization type.
We often think of data as numeric, but it can also be text, images, qualitative, time-based, spatial, and more. The best type of visualization for your research will depend on the data you're using and what you want to show on your visualization.
The most important thing to remember about data visualization is that they are meant to make data easier to understand. Do not inadvertently make the data harder to understand with a confusing or overly complicated visual. The more you create data visualizations, the better you'll become at clarifying the dataset with the visual. See Making an Effective Data Visualization for examples.
When choosing your visualization, consider the following:
A great place to research data visualizations and find ones suitable to your goals is the Data Visualization Catalogue. You can search by function to see those appropriate to your data type or general visualization method.
