Better layouts for tar_visnetwork

[mem48]

I case anybody else has this problem I used

net = tar_network(TRUE)
nodes = net$vertices
edges = net$edges

names(nodes)[1] = "id"
nodes$label = nodes$id

visNetwork(nodes, edges) %>%
  visEdges(arrows = "to") %>% 
  visIgraphLayout(layout = "layout_with_sugiyama", smooth =TRUE)

Which gives access to all the layouts described in https://igraph.org/r/doc/layout_.html

tar_network() returns a visNetwork object that you can modify directly. And tar_network() returns the node and edge information so custom graphs can be created.

I haven't seen a way to achieve a hierarchical layout in visNetwork which is as nice as the mermaid.js graph in terms of the positioning of the edges. I will consider it if a really good set of options becomes available, but as far as I know visNetwork does not support this.
