Tell us what’s happening:
I am making a mistake somewhere but can’t see where. Can I get helped please?

Your code so far


<body>
  <script>
    const dataset = [
                  [ 34,     78 ],
                  [ 109,   280 ],
                  [ 310,   120 ],
                  [ 79,   411 ],
                  [ 420,   220 ],
                  [ 233,   145 ],
                  [ 333,   96 ],
                  [ 222,    333 ],
                  [ 78,    320 ],
                  [ 21,   123 ]
                ];
    
    const w = 500;
    const h = 500;
    const padding = 60;
    
    const xScale = d3.scaleLinear()
                     .domain([0, d3.max(dataset, (d) => d[0])])
                     .range([padding, w - padding]);
    
    const yScale = d3.scaleLinear()
                     .domain([0, d3.max(dataset, (d) => d[1])])
                     .range([h - padding, padding]);
    
    const svg = d3.select("body")
                  .append("svg")
                  .attr("width", w)
                  .attr("height", h);
    
    svg.selectAll("circle")
       .data(dataset)
       .enter()
       .append("circle")
       // Add your code below this line
       .attr("cx", (d) => xScale(d[0]) + 5)
       .attr("cy", (d) => yScale(d[1]) + 5)
       
       // Add your code above this line
       
    svg.selectAll("text")
       .data(dataset)
       .enter()
       .append("text")
       .text((d) =>  (d[0] + ", "
 + d[1]))
       // Add your code below this line
       .attr("x", (d) => xScale(d[0] + 10))
       .attr("y", (d) => yScale(d[1]))
       
       
       // Add your code above this line
  </script>
</body>

There is no need to add + 5.

And also you need to give a radius of 5 to the circles:

.attr('r', 5)
