Tutorial for Flat , a Python library that can be used to create layouts and graphics. This is from the website, with commenting above each line:

   from flat import rgb, font, shape, strike, document
   # prepare some invariants which we are going to use later, like the body typeface, some RGB color or a typeface we open from a font file
   red = rgb(255, 0, 0)
   lato = font.open('Lato-Reg.otf')
   figure = shape().stroke(red).width(2.5)
   headline = strike(lato).color(red).size(20, 24)
   
   # Next is the basic document hierarchy with just one page that can have items be placed into
   d = document(100, 100, 'mm')
   p = d.addpage()
   p.place(figure.circle(50, 50, 20))
   p.place(headline.text('Hello world!')).frame(10, 10, 80, 80)
   # create a .png
   p.image(kind='rgb').png('hello.png')
   # create an .svg
   p.svg('hello.svg')
   # create a .pdf
   d.pdf('hello.pdf')

Running this scripts produces three files, hello.png, hello.svg and hello.pdf
