Size circles by area

Three stations have 12, 24 and 30 docks. Their circles use the number of docks as the radius, so the biggest looks far too big.

Make the circle's area follow the number of docks, with the largest circle a radius of 16.

What Check tests

  1. Three circles are drawn
  2. The 30-dock circle has radius 16
  3. The 12-dock circle has about 40% of the biggest area
