Exploring the "Big mtcars" dataset
This application allows you to build your own dataviz for #TidyTuesday, 2019-10-15.
Tidy Tuesday is a weekly social data project in R. Find more about this project on rfordatasci.com and on the GitHub repo.
This week dataset is a larger version of the well-known mtcars dataset. With this application, you'll be able to build your own {ggplot2} graph out of this dataset.
On each plot, once it's rendered, you'll be able to see the code used by clicking on the image. You can use it as a starting point for more customisation.
For a deeper understanding of the dataset, feel free to unfold the data dictionnary on the bottom of this page.
