Reproducible Path Diagrams (Graphviz and DOT in Stata)

I have written a package named `diagram` (installable through GitHub only, at the moment). Earlier I wrote the same package for R, called DOT.

`diagram` can:

1. Render `Graphviz` diagrams in Stata
2. Render path diagrams written in `DOT` markup language
3. Change the resolution of the diagram to any size
4. Export the graph as raster or vector graphics as pdf, png, bmp, gif, and jpeg

The package can have many applications in drawing reproducible SEM diagrams, visualizing networks data, etc.

The package includes 3 example programs for generating a dynamic diagram for the `sem` and `gsem` commands in Stata, generating a dynamic diagram from the dataset, and also visualizing ado programs based on called programs (i.e. nested ado-programs).

If you are interested, send me an email and I will also share the manuscript I have written for Stata Journal (haven't submitted it yet, want to read it again in a week or two, so I appreciate feedback and suggestions).

Here is an example of rendering a DOT file that exists in the example directory:
