In this demo, I use gtrendsR, an R package available at Cran-R, to pull data from Google Trends, then apply some statistical methods for search trend analysis. To reproduce this work, you need to install R software with gtrendsR. The package ggplot2 is also required for data visualization. This web page was developed using C# with Ajax technology for frontend and R software for backend, allowing Interactive Visualization. Connection between C# and R was done using Rserve package.
