使用 plotly 或 Network 3D 将 igraph 转换为交互式绘图

Question

我正在寻找将 ggraph 对象转换为迭代力网络的示例或教程。

首先，我尝试使用 plotly::ggplotly 函数转换为 plotly 对象。但似乎 plotly 不能很好地处理这种转换并且错过了边缘。

但是我找到了network3D，我可以将一个igraph对象转换成一个network3D对象，但这不是我想要的。而且这个包的功能太冗长了。无论如何，没有从ggraph对象转换的函数。

所以，我的问题很基础，但是...您知道创建交互式 ggraph 网络的任何方法吗？

谢谢

尝试 ggiraph package, it works with ggraph as you can see in the example here（页面底部）。

为了以后参考（如果上面的link可能会死），这里是ggiraph的例子（不是我的代码）：

library(ggraph)
library(igraph)
library(ggiraph)

actors <- data.frame(
  name = c("Alice", "Bob", "Cecil", "David", "Esmeralda"),
  age = c(48,33,45,34,21),
  gender = c("F","M","F","M","F")
)
relations <- data.frame(
  from = c("Bob", "Cecil", "Cecil", "David", "David", "Esmeralda"),
  to = c("Alice", "Bob", "Alice", "Alice", "Bob", "Alice"),
  same.dept = c(FALSE,FALSE,TRUE,FALSE,FALSE,TRUE),
  friendship = c(4,5,5,2,1,1),
  advice = c(4,5,5,4,2,3)
)

g <- graph_from_data_frame(relations,
       directed = TRUE, vertices = actors)

z <- ggraph(g, layout = 'linear', circular = TRUE) +
  geom_edge_arc(color = "red", edge_width = .2) +
  geom_point_interactive(size = 5,
    mapping = aes(x = x, y = y, data_id = gender,
                  tooltip = paste0(name, ": ", age, "y.o."))
  ) + theme_graph()

girafe(ggobj = z, width_svg = 5, height_svg = 5,
       options = list(opts_sizing(rescale = FALSE)))

plotly好像还不支持ggraph，不过你可以跟踪进度here。

使用 plotly 或 Network 3D 将 igraph 转换为交互式绘图

Convert ggraph to interative plot with plotyly or Network3D

interactive

r

plotly

force-layout

ggraph
