Overlays with lavaan and graph

I am having trouble generating readable plots from Lavaan in R. I have a fitted model that I try to plot with graph_sem from the tidySEM library. The plots I generate have all of the independent variables overlaid which limits readability (please see attached sreenshot). I would like to have the dependent variable (called X1) on one layer, and all of the independent variables (X2-X6) on another one.

code:

library(lavaan)
library(tidySEM)

data = data.frame(replicate(7,sample(0:1,1000,rep=TRUE)))
head(data)

model <- '

# Model data here
X1 ~ X2   X3   X4   X5    X6

'

model_fit.sem <- sem(model, data=data, group = 'X7')
summary(model_fit.sem)

graph_sem(model_fit.sem, sig = 0.05)

Result:

You can specify a layout in graph_sem

library(lavaan)
library(tidySEM)

model <- 'X1 ~ X2   X3   X4   X5   X6'

sem(model, data, group = "X7") %>%
  graph_sem(layout = get_layout("",   "",   "X1", "",   "",
                                "",   "",   "",   "",   "",
                                "X2", "X3", "X4", "X5", "X6", rows = 3))
