CorrelCon Advanced Session

Building a modularized Shiny app with the golem 📦 and html widgets

• Session: Data Visualization
• Date: November 7th 2020, 2:30PM (UTC+1)
• Speaker: Cédric Scherer (Data Visualization Designer & Computational Ecologist)

Outline

In this session, I introduce you to modularized Shiny apps and a library called {golem} that simplifies the process of developing roduction-grade applications. I will also give an overview of html widgets that are useful for designing your app and allow for interactive charts and an overall nice user experience. I am going to demonstrate the possibilities using our Shiny app from the LC Berlin that recently won the CorrelAidX challenge.

Example App with Interactive Visualizations

You can have a look at the final example application we are going to build on shinyapps.io.
