There was some chatter on the twitters this week about a relatively new D3-based charting library called TauCharts (also @taucharts). The API looked pretty clean and robust, so I started working on an htmlwidget for it and was quickly joined by the Widget Master himself, @timelyportfolio.
TauCharts definitely has a “grammar of graphics” feel about it and the default aesthetics are super-nifty While the developers are actively adding new features and “geoms”, the core points (think scatterplot), lines and bars (including horizontal bars!) geoms are quite robust and definitely ready for your dashboards.
Between the two of us, we have a substantial part of the charting library API covered. I think the only major thing left unimplemented is composite charts (i.e. lines + bars + points on the same chart) and some minor tweaks around the edges.
While you can find it on github and do the normal:
or, even use the official initial release version:
Believe it or not, there are two   questions on @StackOverflowR about how to make QR codes in R. I personally think QR codes are kinda hokey, but who am I to argue with pressing needs of the #rstats community?

There are a few functions in the package, but the following would be my guess as to how most folks would use it (well, two folks, anyway):
