r - Rstudio - semPlot（lavaan）似乎无论如何都会输出一个不可读的图（尽管事实上是正确的）

Question

我有一个包含 5 个潜在因素的理论框架，每个因素有 10 个问题（大 5，性格问卷）。我想创建一个包含所有 10*5 = 50 个问题和 5 个潜在因素的 semPlot，并可视化它们之间的关系。然而，由于存在大量变量，无论我做什么，情节都是不可读的，而且质量非常低。

这是我的代码（我创建了虚拟 DF）：

df2 <- data.frame(O1 = seq(1,16,by=2), 
                  O2 = seq(1,16,by=2),
                  O3 = seq(1,16,by=2), 
                  O4 = seq(1,16,by=2), 
                  O5 = seq(1,16,by=2),
                  O6 = seq(1,16,by=2), 
                  O7 = seq(1,16,by=2),
                  O8 = seq(1,16,by=2), 
                  O9 = seq(1,16,by=2), 
                  O10 = seq(1,16,by=2),
                  C1 = seq(1,16,by=2), 
                  C2 = seq(1,16,by=2),
                  C3 = seq(1,16,by=2), 
                  C4 = seq(1,16,by=2), 
                  C5 = seq(1,16,by=2),
                  C6 = seq(1,16,by=2), 
                  C7 = seq(1,16,by=2),
                  C8 = seq(1,16,by=2), 
                  C9 = seq(1,16,by=2), 
                  C10 = seq(1,16,by=2),
                  E1 = seq(1,16,by=2), 
                  E2 = seq(1,16,by=2),
                  E3 = seq(1,16,by=2), 
                  E4 = seq(1,16,by=2), 
                  E5 = seq(1,16,by=2),
                  E6 = seq(1,16,by=2), 
                  E7 = seq(1,16,by=2),
                  E8 = seq(1,16,by=2), 
                  E9 = seq(1,16,by=2), 
                  E10 = seq(1,16,by=2),
                  A1 = seq(1,16,by=2), 
                  A2 = seq(1,16,by=2),
                  A3 = seq(1,16,by=2), 
                  A4 = seq(1,16,by=2), 
                  A5 = seq(1,16,by=2),
                  A6 = seq(1,16,by=2), 
                  A7 = seq(1,16,by=2),
                  A8 = seq(1,16,by=2), 
                  A9 = seq(1,16,by=2), 
                  A10 = seq(1,16,by=2),
                  N1 = seq(1,16,by=2), 
                  N2 = seq(1,16,by=2),
                  N3 = seq(1,16,by=2), 
                  N4 = seq(1,16,by=2), 
                  N5 = seq(1,16,by=2),
                  N6 = seq(1,16,by=2), 
                  N7 = seq(1,16,by=2),
                  N8 = seq(1,16,by=2), 
                  N9 = seq(1,16,by=2), 
                  N10 = seq(1,16,by=2))



model_fa <- ' Openness  =~ O1 + O2 +O3 + O4 + O5 + O6 + O7 + O8 + O9 + O10 
              Contientiousness =~ C1 + C2 + C3 + C4 + C5 + C6 + C7 + C8 + C9 + C10
              Extraversion   =~ E1 + E2 + E3 + E4 + E5 + E6 + E7 + E8 + E9 + E10
              Agreeableness   =~ A1 + A2 + A3 + A4 + A5 + A6 + A7 + A8 + A9 + A10
              Neuroticism   =~ N1 + N2 + N3 + N4 + N5 + N6 + N7 + N8 + N9 + N10'

#fit model - select just items
fit_cfa <- cfa(model_fa, data = df2, 
               std.lv=TRUE)

semPaths(fit_cfa, what = 'par', weighted = FALSE, layout = 'tree', nCharNodes = 1,
         residuals = F, thresholds = F, curvePivot=TRUE, rotation = 2, sizeMan = 3)

无论我改变什么，我都会得到一个难以理解的情节。我可以做一些“堆叠”或“躲避”，或者可能是分层的树状结构吗？

还有，为什么质量这么差？我可以更改分辨率吗？
