Guidelines

What type of data visualization should I use?

The best format for data visualization will depend on the type of data and results you wish to display, as well as the medium in which they will be displayed. For example, online interfaces allow for more dynamic visualizations than printed articles.

The DIME Analytics team has created a | Stata Visual Library for Impact Evaluation which shows examples of graphs and provides the codes used to create them. You can contribute to the library on our github.

R has many options for data visualization. Here are some useful packages:

  • ggplot2: this is the go-to package for static plots. Here is a list of ggplot2 visualizations with full R code.
  • plotly: creates interactive graphs, and is integrated with ggplot.
  • gganimate: allows users to create animated GIFs from ggplot plots.
  • Highcharter: this package is a wrapper for the Highcharts JavaScript library.
  • Leaflet: an R wrapper to one of the most popular open-source libraries for interactive maps.
