:cloud: htmlwidgets for D3js Word Cloud Layout

d3wordcloud

What is it?

d3wordcloud is a wrapper for the Word Cloud Layout by Jason Davies based on htmlwidgets.

How it works?!

The main function d3wordcloud needs only words and freqs. Just like the old good wordcloud package. See demo here.

library("d3wordcloud")
words <- c("I", "love", "this", "package", "but", "I", "don't", "like", "use", "wordclouds")
freqs <- sample(seq(length(words)))

d3wordcloud(words, freqs)

How can you get it?

I know! you already know how to install it

devtools::install_github("jbkunst/d3wordcloud")
