D3 JavaScript Network Graphs from R

Version 0.1.8

This is a port of Christopher Gandrud's d3Network package to the htmlwidgets framework.

This README includes information on set up and a number of basic examples. For more information see the package's main page.

Usage

Here's an example of simpleNetwork:

# Create fake data
src <- c("A", "A", "A", "A", "B", "B", "C", "C", "D")
target <- c("B", "C", "D", "J", "E", "F", "G", "H", "I")
networkData <- data.frame(src, target)

# Plot
simpleNetwork(networkData)

Here's forceNetwork:

# Load data
data(MisLinks)
data(MisNodes)

# Plot
forceNetwork(Links = MisLinks, Nodes = MisNodes, Source = "source",
             Target = "target", Value = "value", NodeID = "name",
             Group = "group", opacity = 0.4,
             colourScale = "d3.scale.category20b()")

Here's sankeyNetwork using a downloaded JSON data file:

# Load energy projection data
library(RCurl)
URL <- "https://raw.githubusercontent.com/christophergandrud/networkD3/master/JSONdata/energy.json"
Energy <- getURL(URL, ssl.verifypeer = FALSE)

# Convert to data frame
EngLinks <- JSONtoDF(jsonStr = Energy, array = "links")
EngNodes <- JSONtoDF(jsonStr = Energy, array = "nodes")

# Plot
sankeyNetwork(Links = EngLinks, Nodes = EngNodes, Source = "source",
            Target = "target", Value = "value", NodeID = "name",
            fontSize = 12, nodeWidth = 30)

Saving to an external file

Use saveNetwork to save a network to stand alone HTML file:

library(magrittr)

simpleNetwork(networkData) %>% saveNetwork(file = 'Net1.html')
