Chapter 10 Introduction

Google Trend Visualization application link (https://loankimrobinson.shinyapps.io/google_trend/)

In these chapters you will find many useful techniques. We will use a free tool provided by Google to analyze the popularity of top searches on the Google search engine. The gtrendsR package is an interface for retrieving and displaying the information returned by Google Trends online. You can view trends (number of hits) over time and a geographical representation of the results.

I used the R shinydashboard (https://rstudio.github.io/shinydashboard/) and shinydashboardPlus (https://rinterface.github.io/shinydashboardPlus/) packages for this application. As a key technique, you will learn how to take data from Google Trend (https://cran.r-project.org/web/packages/gtrendsR/gtrendsR.pdf) in your application and convert it to interactive visualizations with D3 JavaScript Network and choropleths. We will apply the plotly (https://plotly.com/r/) and ggplot2 packages.

Let’s start working on your app development workflow.
