“Building ractives is so addictive it should be illegal!”
clickme is an amazing R package. I was not sure what to expect when I first saw Nacho Caballero’s announcement. I actually was both skeptical and intimidated, but neither reaction was justified. The examples prove its power, and his wiki tutorials ease the noobie difficulties. Very similar to shiny, clickme serves as an integration point for ht...

Old Price Tables in Modern d3 Visualization
In my post Dust off 130 Year Old Gold Books on Google Bookshelf, I reproduced some of the old and way out of copyright price tables from the appendices in Gold and Prices Since 1873 by James Laurence Laughlin using latticeExtra xyplot. Now, with the clickme multiline d3 ractive built in my last post “Building ractives is so addictive it should ...

Tables Are Like Cockroaches
As much as I would like to completely replace all tables with beautiful, intuitive, and interactive charts, tables like cockroaches cannot be eliminated. Based on this very interesting discussion on the Perceptual Edge forum with source Exploring the Origins of Tables for Information Visualization, tables date back to 1850 BCE. The paper conclude...

This has been an exciting week for d3.js and R with the release of vega by the data vis powerhouses at Trifacta launch of clickme and already significant rewrite to accommodate vega inception of a very promising d3 templates DexCharts described in multiple posts.

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...

d3 <- R with rCharts and slidify
I believe that the NY Times interactive feature 512 Paths to the White House is one of the best visualizations of all time. It is even better when we have details on the process of creating this marvel. Although the graphic is not suited for other data sources (please tell me if this is not correct), I just could not resist using the amazin...

R creates d3/javascript charts in Ipython Style Notebook
I am not sure I have ever done a post like this, but I was so blown away I had to do this post simply to embed this amazing Youtube video from the author of the R packages rCharts and slidify. Watch this screencast as he creates d3/raphael charts from R using rCharts integration with polycharts, nvd3, xCharts, and morris. To top it off, he do...

Changing The Presidential Election with R in the Browser
After I finished with the tutorial post d3 and then saw R creates d3/javascript charts in Ipython Style Notebook, a light clicked. I could finally answer the lingering question I have had ever since I saw the NYT 512 Path to the White House brilliantly created by Mike Bostock and Shan Carter with d3. What would happen if different states had ...

Old Post with New d3 Life–GARCH and MA Performance
Parallel coordinates become much more useful when they are interactive, so I recreated one of my favorite blog posts “Trend is Not Your Friend” Applied to 48 Industries and convert the chart to a living breathing d3 parallel coordinates chart courtesy of Ramnath Vaidyanathan’s rCharts and Kai Chang’s d3.parcoords. I will convert the scatt...

Japan – JGB Yields–More Lattice Charts
This blog is littered with posts about Japan. In one sentence, I think Japan presents opportunity and is a very interesting real-time test of much of my macro thinking. Proper visualization is absolutely essential for me to understand all of the dynamics. The R packages lattice and the new rCharts give me the power to see. I thought some of my re...
