I want to create a line chart using React and D3, similar to the one depicted in this image.
Presently, I have partially implemented the chart with the code provided below. You can see it here.
The code snippet I've developed so far is outlined as follows -
import React, { Component } from "react";
import * as d3 from "d3";
const width = 400;
const height = 350;
const margin = { top: 20, right: 8, bottom: 20, left: 35 };
// Rest of the code...</questionbody>
<exquestionbody>
<div class="question">
<p>I am aiming to construct a line chart utilizing React and D3 like the design displayed below.

.scaleBand()
.domain(data.map(d => d.price))

.padding(1);
// set domains on the scales

yScale.domain(demandMax);
const lineGenerator = d3
.line()

const line = [

return { line, xScale, yScale, data };
}

this.xAxis.scale(this.state.xScale);
d3.select(this.refs.xAxis).call(this.xAxis);

render() {
console.log(this.state.line);
console.log(this.state.data);
return (
<svg width={width} height={height}>
{this.state.line.map((d, i) => (
<path key={i} d={d.path} stroke={d.stroke} fill={d.fill} />
))}
<g ref="xAxis" transform={`translate(0, ${height - margin.bottom})`} />
<g ref="yAxis" transform={`translate(${margin.left}, 0)`} />
</svg>
);
}
}

Upon hovering over other points, the dotted lines correspond to those points. How can I achieve this using D3 in React? I'm struggling to find a solution.
