Many of the packages for these types of interactive graphics were developed by people
at R Studio, and they have an excellent website
with more information about the
htmlwidgets family. This website links through to tutorials for each package, including
DT, plotly, and leaflet, with lots of examples and the code behind them.
This website also has a gallery, with great examples.
Lots of people are using htmlwidgets to create interesting visualizations through R,
and they will often blog about what they did. If you want more examples of how to
create visualizations with a certain package (e.g., leaflet), it’s worth googling
something like “blog post R leaflet example.”29 Some of the htmlwidgets R packages
have the same name as the Javascript library they’re associated with, so be sure to
include “R” in your Google search, so you’ll find examples in the right programming
language.
Once you’ve worked some with the htmlwidgets packages, you should also check out
Shiny. Shiny allows you to create much more complex
interactive graphics in R—actual
web applications, where the R code to create the visualization is re-run when the user
interacts with elements of the visualization. To get an idea of the things you can
create with Shiny, you should check out the Shiny gallery
and Show Me Shiny.
