visNetwork htmlwidget replaced with static image

For instance at: https://reconlearn-ld.netlify.com/post/simulated-evd-early.html

after the command line plot(x, node_shape = "sex", shapes = c(male = "male", female = "female"), selector = FALSE) the plot should be a htmlwidget, not a png.

See https://reconlearn.netlify.com/post/simulated-evd-early/ for the corresponding version on the old site.
