| Argument | Description |
|---|---|
g | An object of class graph as returned by graph or a graph_proxy as returned by a function of the same name. |
data | A data.frame containing nodes data. |
id | The bare column names containing the nodes ids. |
... | Any other bare named column containing meta data to attach to the nodes. |

if the variables x , y , and z
are passed the rendered visualisation is stable 2/3D and
the force layout algorithm is not run.

Examples
graph_data <- make_data()
graph() %>%
graph_nodes(graph_data$nodes, id)
# using a shiny proxy
library(shiny)
data1 <- make_data(150)
data2 <- make_data(50)
# nodes that do not overalp
# 120 = 30 new nodes added
noverlap <- 120
data2$nodes$id <- as.integer(data2$nodes$id) + noverlap
data2$links$source <- as.integer(data2$links$source) + noverlap
data2$links$target <- as.integer(data2$links$target) + noverlap
ui <- fluidPage(
actionButton("add", "add"),
graphOutput("g", height = "90vh")
)
server <- function(input, output) {
output$g <- render_graph({
graph(data1)
})
observeEvent(input$add, {
graph_proxy("g") %>%
graph_nodes(data2$nodes, id) %>%
graph_links(data2$links, source, target)
})
