Many statistical papers or articles present very nice draws of graphical models.
Example: this on LDA from wikipedia
or this, pg 7, directly from the paper:

I am now writing a paper where I have to introduce a new graphical model. If I try to draw it, say with paint, something very horrible comes out (see my other posts)
So I am wondering: which tool use statisticians to draw such nice models in their papers?
Look at this post of mine: http://stats.stackexchange.com/questions/272122/fitting-partially-observed-mixture-models
the quality of the chart is very poor, if compared with the linked images, and I can not add it on a paper.
