To make a network diagram with tooltips using igraph, ggraph, and networkD3, follow these steps:
```{r} library(igraph)
edges <- data.frame(from=c(1,2,3), to=c(2,3,1)) nodes <- data.frame(id=1:3, label=c("A","B","C")) graph <- graphfromdata_frame(edges, vertices=nodes, directed=FALSE)
plot(graph)
2. Next, use ggraph to create a layout for your graph. This will arrange your nodes and edges in a visually appealing way. Use the code below to create a layout:
```{r}
library(ggraph)
layout <- ggraph(graph, layout = "circle") +
geom_edge_link() +
geom_node_point() +
theme_void()
layout
```{r} library(networkD3)
nodes$tooltip <- c("Color: red", "Color: blue", "Color: green")
networkD3::forceNetwork( Links = data.frame(from = get.edgelist(graph)[,1], to = get.edgelist(graph)[,2]), Nodes = nodes, Source = "from", Target = "to", NodeID = "id", Group = "id", radiusCalculation = JS("Math.sqrt(d.nodesize)+5"), linkDistance = 100, fontSize = 12, opacity = 0.9, zoom = TRUE, legend = TRUE, bounded = TRUE, showLabels = TRUE, linkAlpha = 0.5, nodesize = 20, fontFamily = "serif", linkWidth = 2, linkColour = "grey", NodeProps = "tooltip", NodeColour = "label", colourScale = "{}", legendPosition = "top", legendWidth = 200, legendFontSize = 15 ) ```
