#' Create Interactive Path Diagrams for Lavaan Models
#'
#' The `plot_lavaan` function creates path diagrams for lavaan model.
#' The created paths diagrams  are interactive. 
#' That is, their appearance can be customized easily, for example, by dragging 
#' around nodes representing variable with the mouse.
#'
#' @param fit A lavaan model, as returned by the functions `lavaan`, `sem`, or `cfa` from the `lavaan` package.
#'
#' @param where A character string to specify where the path diagram should be shown.
#' The default value "gadget" shows it directly in Rstudio. For "browser", it's shown in your default browser.
#' For non-RStudio users, the parameter has no effect, and the path diagram is always shown in the browser.
#' @return nothing
