High performance R libraries for interactive graphics
My current go-to are some graphics from Rstudio's flexdashboard and a set of relatively well-maintained packages: 


  Leaflet, a library for creating dynamic maps that support panning and
  zooming, with various annotations like markers, polygons, and popups.
  
  dygraphs, which provides rich facilities for charting time-series data
  and includes support for many interactive features including
  series/point highlighting, zooming, and panning.
  
  Plotly, which via its ggplotly interface allows you to easily
  translate your ggplot2 graphics to an interactive web-based version.
  
  rbokeh, an interface to Bokeh, a powerful declarative Bokeh framework
  for creating web-based plots.
  
  Highcharter, a rich R interface to the popular Highcharts JavaScript
  graphics library.
