Your code so far

    const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];
    const w = 500;
    const h = 100;
    const svg = d3.select("body")
                  .attr("width", w)
                  .attr("height", h);
       .attr("x", (d, i) => {
         // Add your code below this line
      .style("height", (d) => d+"px")
         // Add your code above this line
       .attr("y", 0)
       .attr("width", 25)
       .attr("height", 100);

Link to the challenge:

Note that you already writing a callback, function, so you can’t start the body of the function with a dot

also note that this is what you should be doing:

Change the x attribute callback function so it returns the index times 30.
