And have a look to multiple R examples, vis.js documentation (visDocumentation).

• Update network in shiny using visNetworkProxy (lot of functionalities, ?visNetworkProxy)

• Enabled highlightNearest & selectedBy with icons and / or image

• Enabled hover forhighlightNearest and fix/improve performance with high degree

• multiple groups selection / title to network & legend / ionicons icons possibilities. See ?addIonicons

• new function visSave to save as html and visExport to save as png/jpeg (shiny and browser only)

• Better performance with visIgraphLayout

• have a look to visIgraph to plot visNetwork object from igraph object (Little bit experimental)

• Add custom legend with visLegend

install.packages("visNetwork")

# devtools::install_github("datastorm-open/visNetwork") for developpement version

require(visNetwork)
?visNetwork

# minimal example
nodes <- data.frame(id = 1:3)
edges <- data.frame(from = c(1,2), to = c(1,3))
visNetwork(nodes, edges)
