Create an Area chart using Recharts in React JS

Rechart JS is a library that is used for creating charts for React JS. This library is used for building Line charts, Bar charts, Pie charts, etc, with the help of React and D3 (Data-Driven Documents).  

Prerequisites:

• React JS
• React Recharts

Approach to create Area Chart:

To create an Area Chart using Recharts, we create a dataset that contains actual data. Then we define the slices using the area element with data property which will have the data of the dataset created and with datakey property which is the property name with a value for the slices.

• Chart Rendering: Create a React component (App) to render an AreaChart using 'recharts,' specifying dimensions, sample data, and visual configurations for student counts.
• Data Visualization Display: Render the configured AreaChart in the App component, displaying a visual representation of student counts for entities like 'Geeksforgeeks' and 'Technical scripter' with colored areas.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command.

npx create-react-app foldername

Step 2: After creating your project folder i.e. foldername, move to it using the following command.

cd foldername

Step 3: After creating the ReactJS application, Install the required modules using the following command.

npm install --save recharts

Project Structure:

The updated dependencies in package.json file will look like:

"dependencies": {
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-scripts": "5.0.1",
    "recharts": "^2.10.1",
    "web-vitals": "^2.1.4",
}

Example: Now write down the following code in the App.js file.

import React from 'react';
import {
AreaChart, Area,
CartesianGrid, XAxis, YAxis
} from 'recharts';

const App = () => {

    // Sample data
    const data = [
        { name: 'Geeksforgeeks', students: 400 },
        { name: 'Technical scripter', students: 700 },
        { name: 'Geek-i-knack', students: 200 },
        { name: 'Geek-o-mania', students: 1000 }
    ];

    return (
        <AreaChart width={600} height={600} data={data}>
            <Area dataKey="students"
                fill="green" stroke="green" />
            <CartesianGrid stroke="#ccc" />
            <XAxis dataKey="name" />
            <YAxis />
        </AreaChart>
    );
}

export default App;

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/
