Banging on the JGBs

Since I have not posted in quite a while, I wanted to let everyone know that I am still alive and kicking.  The resurrection of excitement (opportunity) in the markets, quarterly reporting cycle, and the overwhelming number of unbelievable R/javascript releases have kept me from writing something good enough to justify a post.   In the markets, Japan and gold bring a smile to my face.    Nothing particularly new on the quarterly reporting cycle, but I have been watching the interesting ideas at closely, and I have enjoyed learning a little about  Nothing though impresses me as much as all of the R and javascript packages that have been announced over the last two weeks.  I mentioned them in my post d3 Lifeline from vega and clickme, but I forgot to include Introducing the healthvis R package – one line D3 graphics with R from Jeff Leek who taught, and rCharts was not yet released.  rCharts reminded me of the very special slidify package that I have to my own detriment not used until now.  I strongly, strongly recommend readers to thoroughly look at  rCharts  and slidify.  Just to make sure everyone sees all of these, I have relisted them and added new links below with the Twitter announcements.


Announcing Vega, a new visualization grammar built on #d3js! Design reusable chart components in a JSON format

rCharts from the same creator as slidify

@lisaczhang I wrote an R package wrapping functionality of Polycharts for R users.

@xieyihui I'd love your feedback on clickme, an R package to populate JS visualizations using #knitr

Our package is announced today!

Now to show some of the results from my experiments, I will list some bl.ocks below.  The primary data source for all of these has been the Japanese Government Bond (JGB) yield data provided by the Japanese Ministry of Finance.  I will discuss the reasons for choosing JGBs in a much more thorough later post.  I would love thoughts on JGBs and my experiments.

  1.  JGB Yields in Small Multiples with clickme ractive
  2.  JGB Yield Curve with a vega spec and clickme ractive
  3.  JGB Yields Line Chart with a vega spec and clickme ractive

Some of my other more basic experiments are here.  These might be helpful to anyone not yet familiar with these new resources.



I’ll be back soon with what I hope is a very impressive slidify created market-related post.  Until then, please let me know what you think, or show your relevant experiments.


Thanks to everyone that has worked so hard creating these great open source projects.
