Introduction

visNetwork is an R package for network visualization, using vis.js javascript library (http://visjs.org/). All remarks and bugs are welcome on github : https://github.com/datastorm-open/visNetwork.

Features

Based on htmlwidgets, so :

compatible with shiny, R Markdown documents, and RStudio viewer

The package proposes all the features available in vis.js API, and even more with special features for R :

easy to use
custom shapes, styles, colors, sizes, …
works smooth on any modern browser for up to a few thousand nodes and edges
interactivity controls (highlight, collapsed nodes, selection, zoom, physics, movement of nodes, tooltip, events, …)
visualize rpart tree

Installation

Package is now available on CRAN.

install.packages("visNetwork")

# can have new features in development version 
devtools::install_github("datastorm-open/visNetwork")

How does it work ?

visNetwork needs at least two pieces of information :

a nodes data.frame, with id column
an edges data.frame, with from and to columns, which make the link with id

require(visNetwork, quietly = TRUE)
# minimal example
nodes <- data.frame(id = 1:3)
edges <- data.frame(from = c(1,2), to = c(1,3))
visNetwork(nodes, edges, width = "100%")

Need help ?

Besides the help R functions, a vignette is available, and you can access and read the full javascript API from R using visDocumentation():

# javascrtip api
visDocumentation()
vignette("Introduction-to-visNetwork") # with CRAN version
# shiny example
shiny::runApp(system.file("shiny", package = "visNetwork"))
