I am new d3.js .I am trying to run code at this
link.For running this code, I placed that code in index.js file.
d3 = require("d3@5")
height = 500
margin = ({top: 10, right: 10, bottom: 20, left: 40})
data = Object.assign(d3.csvParse(await FileAttachment("data.csv").text(), d3.autoType), {y: "Population"})
groupKey = data.columns[0]
keys = data.columns.slice(1)
x0 = d3.scaleBand()
.domain(data.map(d => d[groupKey]))
.rangeRound([margin.left, width - margin.right])
.paddingInner(0.1)
x1 = d3.scaleBand()
.domain(keys)
.rangeRound([0, x0.bandwidth()])
.padding(0.05)
y = d3.scaleLinear()
.domain([0, d3.max(data, d => d3.max(keys, key => d[key]))]).nice()
.rangeRound([height - margin.bottom, margin.top])
color = d3.scaleOrdinal()
.range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"])
xAxis = g => g
.attr("transform", `translate(0,${height - margin.bottom})`)
.call(d3.axisBottom(x0).tickSizeOuter(0))
.call(g => g.select(".domain").remove())
yAxis = g => g
.attr("transform", `translate(${margin.left},0)`)
.call(d3.axisLeft(y).ticks(null, "s"))
.call(g => g.select(".domain").remove())
.call(g => g.select(".tick:last-of-type text").clone()
.attr("x", 3)
.attr("text-anchor", "start")
.attr("font-weight", "bold")
.text(data.y))
legend = svg => {
const g = svg
.attr("transform", `translate(${width},0)`)
.attr("text-anchor", "end")
.attr("font-family", "sans-serif")
.attr("font-size", 10)
.selectAll("g")
.data(color.domain().slice().reverse())
.join("g")
.attr("transform", (d, i) => `translate(0,${i * 20})`);
g.append("rect")
.attr("x", -19)
.attr("width", 19)
.attr("height", 19)
.attr("fill", color);
g.append("text")
.attr("x", -24)
.attr("y", 9.5)
.attr("dy", "0.35em")
.text(d => d);
}
chart = {
const svg = d3.select(DOM.svg(width, height));
svg.append("g")
.selectAll("g")
.data(data)
.join("g")
.attr("transform", d => `translate(${x0(d[groupKey])},0)`)
.selectAll("rect")
.data(d => keys.map(key => ({key, value: d[key]})))
.join("rect")
.attr("x", d => x1(d.key))
.attr("y", d => y(d.value))
.attr("width", x1.bandwidth())
.attr("height", d => y(0) - y(d.value))
.attr("fill", d => color(d.key));
svg.append("g")
.call(xAxis);
svg.append("g")
.call(yAxis);
svg.append("g")
.call(legend);
return svg.node();
}
After that i called index.js file from html script
<html>
<head>
<title>Visualization 2 (Multiline graph)</title>
<link rel="stylesheet" href="styles.css">
<script src="https://unpkg.com/d3@5.6.0/dist/d3.min.js"></script>
</head>
<body>
<svg width="960" height="500"></svg>
<script src="index.js"></script>
</body>
</html>
I created the data.csv file from array

This code is not giving the required output that is this graph.

How to get the required output.
Update: Code is giving me following error in vizhub
SyntaxError: Unexpected keyword 'const' (57:4)
/index.js (line 57)
53 : .attr("dy", "0.35em")
54 : .text(d => d);
55 : }
56 : chart = {
57 : const svg = d3.select(DOM.svg(width, height));
