To Reproduce
Error in `ggraph::geom_edge_arc()` at manynet/R/map_autograph.R:459:5: ! Problem while setting up geom aesthetics. ℹ Error occurred in the 1st layer. Caused by error in `check_aesthetics()`: ! Aesthetics must be either length 1 or the same as the data (11200). ✖ Fix the following mappings: `edge_linetype`. Run `rlang::last_trace()` to see where the error occurred.
