This presentation is part of the Course Project for the Coursera Developing Data Products class.

The peer-assessed assignment has two parts:
1. Create a Shiny application and deploy it on RStudio’s servers
2. Prepare a reproducible pitch presentation using Slidify or RStudio Presenter

This presentation addresses the second part of the project.

The app helps users choose a car for a trip using the mtcars dataset.

How it works: - Enter trip distance and gasoline price → app computes fuel cost per car - Set a maximum fuel budget → shows only cars under that cost - Further filter by: - Cylinders
- Displacement
- Horsepower
- Transmission
- Sort the resulting table using column arrows

This scatterplot shows the relationship between: - Miles per gallon (mpg) - Displacement (disp) - Weight (wt)
