title: Generate HoneyComb hexagonal patern in Axial coordinates
body: <p>I was searching for am algorithm to generate a HoneyComb of hexagons like this one using axial coordinates : </p>
  
  <p><img src="https://i.stack.imgur.com/Z5LK9.png" alt="this has a radius of 4">
  But I only managed to find generators in Cube coordinates.</p>
  
  <p>I made this question only to share my solution .</p>
