This is a stack setup for diagrams library. The actual code is borrowed from diagrams examples here: https://diagrams.github.io/gallery/Chart.html

$ git clone https://github.com/EugeneN/diagrams-demo.git
$ cd diagrams-demo
$ stack build

$ stack exec diagrams-demo-exe -- -w 400 -h 400 -o result.svg

then open result.svg file with your favorite image viewer. In Linux/X11 you can use

xdg-open result.svg

command. You should see something like this:

Alternatively, you can run:

$ stack exec diagrams-demo-exe -- --help

to see all the options and their descriptions.

1. edit app/Main.hs and add your code
2. stack build
3. stack exec diagrams-demo-exe -- -w 400 -h 400 -o result.svg
4. xdg-open result.svg
5. repeat.
