D3.js is a JavaScript library for manipulating documents based on data. Biovisualize and christopheviau provide two major list of the gallaries of D3.js websites. The github repository also contains a nice list of gallaries. D3.js is the brainchild of NY Times data visualizer Mike Bostock. Bostock also develops an awesome website for visualizating the gists. The web address is bl.ocks.org. It converts gists to live dynamic pages. For example, Prim’s Algorithm IV is a bl.ocks page developed by Mike. The webpage link for this bl.ocks page is http://bl.ocks.org/mbostock/ 76da6085849bff8b6e03. We need to change the bl.ocks.org with gist.github.com to get the gist for that awesome visualization. I have also found that Ramnath also has few bl.ocks. Like to add that Amanda Cox also works with Mike in NY Times in their visualization team. NY Times visualization team creates many superb visualizations in the recent years. Nice listing of d3.js courses is curated by VUDlab.

Docco is a quick-and-dirty documentation generator, written in Literate CoffeeScript. Yihui showes know-how of r-docco in a vignette of knitr. I am basically interested to get the linear style view. The code is here. We have to install docco first. sudo npm install -g docco. We can check the version by docco version. Steps are: → make a folder → create a RMD file following Yihui Rmd file (first few lines) → in R console set the directory by setwd("") → run in console knitr::knit2html(input = "filename.Rmd", output = "filename.md", template = system.file ("misc", "docco-template.html", package = "knitr")) → go to the terminal and cd to the docco folder → run docco filename.md.

Slidify is a nice tool to make slides using RStudio with various javascript templates. It's created and maintained by Ramnath. Steps are pretty simple: → install 'slidify' by using 'devtools' library → go to the folder where '.rmd' file resides → then in console run slidify('filename.rmd') [this step is crucial; as it makes the slidify ready html; if you run knit html you will not get the slidify ready slides] → in console run browseURL('filename.html'). That's all. Here's his slides. I am trying lately using interactive d3 or rcharts in reveal.js. I have found a solution of using d3.js in reveal slides. Another thing I have found is using interactive rCharts in reveal slides. Here's one of my attempt.

rCharts is used to create, customize and publish interactive javascript visualizations from R using a familiar lattice style plotting interface. It's created and maintained by Ramnath. Here's a nice example. rCharts gallery will be a good start for the beginners. The documentation is very helpful to replicate and push the codes online. To publish in rpubs: r1$publish('Scatterplot', host = ’rpubs’). To save html in a folder: r1$save('mychart2.html', standalone = TRUE). Here's one of my attempt. Another one: pedestrian fatalities per 100,000 population.
