React Charts and Graphs with Recharts: Visualize Knowledge Fantastically

Representing knowledge in a chart view is a large topic in Arithmetic and Pc Science. When you have the talent to rework uncooked numbers right into a chart view, it’s a superb illustration that makes customers perceive any complicated knowledge shortly.

Studying to construct a chart in React will elevate your UI and make your software really feel actually skilled.

This React instance contains dashboard visualization to show the next chart view.

1. Gross sales & income pattern within the type of line chart.
2. Product-wise efficiency utilizing column chart.
3. Browser distribution in pie chart.
4. Space chart to visualise customers’ lively time.

It makes use of Recharts library to point out the uncooked knowledge in a graph or chart kind, as proven under.

Foremost React part containing chart parts

The DataVisualization part manages React states and useEffect. It manages the separate state variables for every sort of charts.

The React useEffect fetches the JSON knowledge and set them to bind for the charts.

The chart UI are created as separate parts and used within the dashboard wrapper.

src/parts/DataVisualization.jsx

import { useState, useEffect } from "react";
import Header from "../parts/Header";
import StatsCards from "../parts/StatsCards";
import LineChartBox from "../parts/LineChartBox";
import BarChartBox from "../parts/BarChartBox";
import PieChartBox from "../parts/PieChartBox";
import AreaChartBox from "../parts/AreaChartBox";
import Footer from "../parts/Footer";

const DataVisualization = () => {
  const [lineData, setLineData] = useState([]);
  const [barData, setBarData] = useState([]);
  const [pieData, setPieData] = useState([]);
  const [areaData, setAreaData] = useState([]);
  useEffect(() => {
    fetch("/knowledge/dashboard.json")
      .then((res) => res.json())
      .then((knowledge) => {
        setLineData(knowledge.lineData);
        setBarData(knowledge.barData);
        setPieData(knowledge.pieData);
        setAreaData(knowledge.areaData);
      })
      .catch((err) => console.error("Error loading knowledge:", err));
  }, []);
  return (
    <div className="dashboard-wrapper">
      <div className="dashboard-container">
        <Header />
        <StatsCards />
        <div className="charts-grid">
          <LineChartBox knowledge={lineData} />
          <BarChartBox knowledge={barData} />
          <PieChartBox knowledge={pieData} />
          <AreaChartBox knowledge={areaData} />
        </div>
        <Footer />
      </div>
    </div>
  );
};
export default DataVisualization;

Chart visualization header with trending knowledge playing cards

  <header className="dashboard-header">
    <h1>Knowledge Visualization Dashboard</h1>
    <p>Lovely charts and graphs powered by Recharts in React</p>
  </header>
);
export default Header;

src/parts/StatsCards.jsx

import { TrendingUp, BarChart3, Customers, Exercise } from "lucide-react";
const StatsCards = () => {

    { icon: <TrendingUp strokeWidth={1} />, label: "Total Sales", value: "$24,850", change: "+12.5%" },
    { icon: <BarChart3 strokeWidth={1} />, label: "Revenue", value: "$48,200", change: "+8.2%" },
    { icon: <Users strokeWidth={1} />, label: "Users", value: "12,543", change: "+23.1%" },
    { icon: <Activity strokeWidth={1} />, label: "Growth", value: "34.8%", change: "+5.4%" },
  ];
  return (
    <div className="stats-grid">
      {stats.map((stat, index) => (
        <div key={index} className="stat-card">
          <div className="stat-top">
            <span className="stat-icon">{stat.icon}</span>
            <span className="stat-change">{stat.change}</span>
          </div>

          <p className="stat-label">{stat.label}</p>
          <p className="stat-value">{stat.worth}</p>
        </div>
      ))}
    </div>
  );
};
export default StatsCards;

Line chart to point out the gross sales income graph

• XAxis, YAxis
• Tooltip and Legend
• CartisanGrid
• ResponsiveContainer

The chart is rendered in a ResponsiveContainer block which assist chart scaling primarily based on the viewport measurement. The Tooltip and CartisanGrid will likely be proven on hovering the chart. The X,Y axis and chart legend are very normal a part of the chart view.

The LineChart and Line parts are unique to such a chart. It accepts Recharts attributes to set the stroke width and colour of the road graph.

src/parts/LineChartBox.jsx

import { LineChart, Line, XAxis, YAxis, Tooltip, CartesianGrid, Legend, ResponsiveContainer } from "recharts";
const LineChartBox = ({ knowledge }) => (
  <div className="chart-card">
    <h2>Gross sales & Income Development</h2>
    <ResponsiveContainer width="100%" top={300}>
      <LineChart knowledge={knowledge}>
        <CartesianGrid strokeDasharray="3 3" stroke="#475569" />
        <XAxis stroke="#94a3b8" />
        <YAxis stroke="#94a3b8" />
        <Tooltip />
        <Legend />
        <Line sort="monotone" dataKey="gross sales" stroke="#3b82f6" strokeWidth={1} />
        <Line sort="monotone" dataKey="income" stroke="#10b981" strokeWidth={1} />
      </LineChart>
    </ResponsiveContainer>
  </div>
);
export default LineChartBox;

Bar chart fir displaying efficiency graph

The BarChart and Bar part of the Recharts library are used on this script. The BarChart accepts chart knowledge and Bar aspect requires the colour specification to fill the column bar.

src/parts/BarChartBox.jsx

import { BarChart, Bar, XAxis, YAxis, Tooltip, CartesianGrid, ResponsiveContainer } from "recharts";
const BarChartBox = ({ knowledge }) => (
  <div className="chart-card">
    <h2>Product Efficiency</h2>
    <ResponsiveContainer width="100%" top={300}>
      <BarChart knowledge={knowledge}>
        <CartesianGrid strokeDasharray="3 3" stroke="#475569" />
