Introduction

This app allows users to explore the relationship between various car attributes (like horsepower, weight, etc.) and fuel efficiency (MPG) using the built-in mtcars dataset.

Motivation

Understanding how car characteristics affect fuel consumption can help in designing more efficient vehicles.
The goal is to visualize and model these relationships interactively.

App Functionality

• Input: Choose a variable (e.g., horsepower, weight)
• Output: Scatter plot of MPG vs variable
• Option to add regression line
  
• Output: Summary of linear regression model

summary(lm(mpg ~ wt, data = mtcars))
