    const w = 500;
    const h = 100;

    const svg = d3.select("body")
                  .append("svg")
                  .attr("width", w)

       .enter()
       // Add your code below this line
       .append("text")
       .attr("x", (d, i) => i*30)
       .attr("y", (d, i) => h-3*d-3)
       .text((x) => x)
       .text((y) => y);
       // Add your code above this line
  </script>
