Coursera JHU Week 3 assignment requires to create a web page presentation using R Markdown that features a plot created with Plotly.
The dataset used comes from R4DS Online Learning Community called TidyTuesday. A weekly dataset is published in the site and invites R code enthusiasts to develop data exploration and visualization skills.
For the assignment, I chose the Big mtcars dataset from the EPA. It’s essentially a much much larger and updated dataset covering mtcars, the dataset we all know a bit too well!
Ready, set, go!!
