Hierarchical Edge Budnles about ggraph HOT 3 CLOSED

I'll try to see if I can address these questions adequately:

The hierarchical edge bundles uses a concept called connections; that is, links between edges that do not interfere with how the layout is calculate. A connection can be thought of as the sequence of nodes to travel through to get from the start to the end. In the flare example the class hierarchy makes up the graph structure which end up as a hierarchical layout (that isn't drawn). The import data is then a secondary structure that defines links between nodes in the hierarchy, but isn't part of that hierarchy. For the hierarchical edge bundles the paths defining the connections are detected automatically using the gCon function...

For the second question, this is more an igraph issue, and I suggest you consult the documentation (it's very well documented)

Hope this helps - I'm in the last stage of thesis writing at the moment, so it is a little short...

This was a really useful comment. I was having a hard time using geom_edge_bundle until I realized that flare$edges was a full rooted hierarchy (I only had specific and general classes, but nothing to connect the general classes). Good luck with your thesis!

Glad it made sense - feel free to get back with further questions. I'm planning on adding a wiki once time permits, but until then some of the specifics of the API can be a bit hard to grasp
