Consider: Additional output formats for documents that can be rendered (md, rst, dot, etc.)

Some potential additions:

• [ ] md
  • [ ] -> pdf
  • [ ] -> png/jpg
  • [ ] -> styled HTML
• [ ] rst
  • [ ] -> pdf
  • [ ] -> png/jpg
  • [ ] -> styled HTML
• [ ] dot
  • [ ] -> pdf
  • [ ] -> png/jpg
  • [ ] -> styled html
  • [ ] -> svg
  • [ ] -> monospaced box drawing
  • [ ] (see: graph-easy, a perl project)

For each additional render type, I'll need to lock down dangerous execution possibilities.
