New to Rhombus?

Install Rhombus with raco pkg install rhombus-main[1]
then try this in DrRacket:

#lang rhombus
import:
  rhombus/pict open
let body = ellipse(~width: 100, ~height: 50, ~fill: "salmon")
let tail = triangle(~width: 40, ~height: 5, ~fill: "salmon").rotate(0.5 * math.pi)
let eye = ellipse(~width: 8, ~height: 8, ~fill: "black").pad(~left: -92, ~top: -12)
let fish = overlay(
  beside(body, tail),
  eye
)
fish
