Doing a simple interactive network with the simpleNetwork() function of the networkD3 library


# Load package
library(networkD3)
library(webshot)

# create data:
set.seed(101)
links=data.frame(
    source=c("A","A", "A", "A", "A","J", "B", "B", "C", "C", "D","I"),
    target=c("B","B", "C", "D", "J","A","E", "F", "G", "H", "I","I")
    )
# Plot
graph=simpleNetwork(links)
saveNetwork(graph,file = '#252_interactive_network_chart1.html',selfcontained = T)

# Load package

library(networkD3)

library(webshot)

# create data:

set.seed(101)

links=data.frame(

source=c("A","A", "A", "A", "A","J", "B", "B", "C", "C", "D","I"),

target=c("B","B", "C", "D", "J","A","E", "F", "G", "H", "I","I")

)

# Plot

graph=simpleNetwork(links)

saveNetwork(graph,file = '#252_interactive_network_chart1.html',selfcontained = T)

And we can custom it


simpleNetwork(links,     
        Source = 1,                 # column number of source
        Target = 2,                 # column number of target
        height = 480,               # height of frame area in pixels
        width = 480,
        linkDistance = 120,         # distance between node. Increase this value to have more space between nodes
        charge = -480,              # numeric value indicating either the strength of the node repulsion (negative value) or attraction (positive value)
        fontSize = 22,              # size of the node names
        fontFamily = "serif",       # font og node names
        linkColour = "#666",        # colour of edges, MUST be a common colour for the whole graph
        nodeColour = "red",         # colour of nodes, MUST be a common colour for the whole graph
        opacity = 0.8,              # opacity of nodes. 0=transparent. 1=no transparency
        zoom = T                    # Can you zoom on the figure?
