Interactive Visualizations in R and Tab Switcher

I am familiar with ggplot2, network visualizations using igraph etc...(i.e. static visualizations), but I know pretty much nothing about how to make interactive web visualizations (e.g. charts you can see in a browser). My tool of choice for everything which is statistics is R. Have a look at this webpage

Generating any single plot as a pdf, png, etc...with ggplot2 would be a piece of cake but how

1) to make the plots visible online in the browser

2) have a simple point and click mechanism to switch from one plot to another.

From some googling, I understood I probably need a combination of htmlwidgets and shiny. Meanwhile, can anyone provide me with a snippet with any fake data and a couple of plots I can use as a template for later modification?

Thanks!
