Render a DOT graph

This demo uses the https://crates.io/crates/layout-rs crate (src: https://github.com/nadavrot/layout), wraps it using Rustler, and allows to convert text in DOT Language to SVG.

render = fn file ->
  %Req.Response{status: 200, body: dot_file} =
    Req.get!("https://raw.githubusercontent.com/nadavrot/layout/master/inputs/#{file}")

  dot_file
  |> Dot.to_svg()
  |> Kino.Image.new(:svg)
end

file_selector =
  Kino.Input.select(
    "Please select the file",
    [
      "1", "2", "3", "4", "5", "6", "7", "8", "9",
      "bk", "diamond", "ella", "expr", "heb", "noa",
      "prof", "sched0", "sched1", "self", "small"
    ]
    |> Enum.map(fn u -> {"#{u}.dot", u} end)
  )

render.(Kino.Input.read(file_selector))
