• The shiny application pitched in this presentation is (https://saif178.shinyapps.io/Project1/)

• The Shiny app source code is (https://github.com/Saif178/Course_Project)

• Allows you to visualise the population and life expectancy of US states in using the US State Facts and Figures dataset.

• You can use sliders to select a population and life expectancy range to display and checkboxes to show different regions

• The output is an interactive map of the US showing the states that satisfy the selected criteria.

• A data frame called states was created using the vectors from the US Facts and Figures Dataset.

• A fourth column (hover) was added for the interactivity of the map.

• The slider values and checkbox values are used to filter the dataset using the state.name and state.region columns before creating the map.

• The output is a googlevis interactive map.

• The states turn green when they satisfy the selected criteria (slider and checkboxes)

• When each green state is hovered over, the name and area of the state is displayed.
