As with the previous challenges, make use of D3’s .data() method, passing dataset as an argument.

Hint 2

Ensure that you follow using .data(arg) with .enter()

    const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];
    
    const w = 500;
    const h = 100;
    
    const svg = d3.select("body")
                  .append("svg")
                  .attr("width", w)
                  .attr("height", h);
    
    svg.selectAll("rect")
       // Add your code below this line
        .data(dataset)
        .enter()
        .append("rect")   
       
       
       // Add your code above this line
       .attr("x", 0)
       .attr("y", 0)
       .attr("width", 25)
       .attr("height", 100);
