Questions tagged [ggraph]

ggraph is the "Grammar for Graph Graphics". At the time of writing, it is an actively maintained library for R that builds upon ggplot2 providing support for relational data structures such as networks, graphs and trees. It provides a concept of layouts to aid in the layout of a graph when visualising it.

Additional information, examples, documentation and the source can be obtained from GitHub - ggraph
