Multi-monitor systems (U.S. Population Dynamics) 2. Controller-driven monitor (Art Cultural Exploration) 3. Outputs ## are automatically updated whenever inputs change. This demonstrates ## how a standard R plot can be made interactive by wrapping it in the ## Shiny `renderPlot` function. The `selectInput` function creates the ## input widgets used to control the plot display.

This module will introduce you to Shiny, a framework that integrates with RStudio to construct web-based dashboards.We will work through a number of simple examples of loading data, visualizing it with R's built-in graphics operations, then integrating those visualizations into an interactive Shiny web dashboard, which can be viewed online by anyone with a web browser. Our team designed a R Shiny Leaflet method to select multiple locations on a Leaflet map, useful for bounding box or other selections in your dashboard.
