This short pitch introduces a Shiny app that helps learners explore how car features relate to miles-per-gallon (mpg).
Problem
Beginners need an easy interactive way to visualize how vehicle features affect fuel efficiency.
Idea
A small Shiny app that: - Lets the user choose a predictor (wt, hp, disp, drat)
- Shows a scatterplot (mpg vs predictor)
- Optionally displays a regression line and model summary
# show first 5 rows of the variables used
head(mtcars[, c("mpg", "wt", "hp", "disp")], 5)
How to use the app: 1. Select a predictor variable in the app.
2. View the scatterplot in the Plot tab.
3. Toggle the regression line & model summary in the Model Summary tab. Links (paste after deployment): - Shiny App: (paste your shinyapps.io URL here)
