trying to center:
graph_width <- max(mastery_tree$x) - min(mastery_tree$x)
midpoint_x <- min(mastery_tree$x) + (graph_width/2)
desired_midpoint_x <- 0
shift_x <- desired_midpoint_x - midpoint_x
mastery_tree$x <- mastery_tree$x + shift_x
x_range <- max(mastery_tree$x) - min(mastery_tree$x)
x_lim <- c(min(mastery_tree$x) - 0.1 * x_range, max(mastery_tree$x) + 0.1 * x_range)
plot <- ggraph(graph, layout = 'manual', node.positions = mastery_tree)
+ geom_edge_link()
+ geom_node_point(size = 3)
+ geom_node_text(aes(label = label), repel = TRUE, size = 3)
+ expand_limits(x = x_lim)
