Solution
To solve the challenge, use:
<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")
.attr("cx", (d) => xScale(d[0]))
.attr("cy",(d) => yScale(d[1]))
.attr("r", (d) => 5);
svg.selectAll("text")
.data(dataset)
.enter()
.append("text")
.text((d) => (d[0] + "," + d[1]))
.attr("x", (d) => xScale(d[0] + 10))
.attr("y", (d) => yScale(d[1]))
const xAxis = d3.axisBottom(xScale);
const yAxis = d3.axisLeft(yScale);
svg.append("g")
.attr("transform", "translate(0," + (h - padding) + ")")
.call(xAxis);
svg.append("g")
.attr("transform", "translate(" + padding + ", 0)")
.call(yAxis);
