Introduction: 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).
To create Donut Chart using Recharts, we create a dataset that contains actual data. Then we define the slices using donut 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.
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: It will look like the following.
Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.
Javascript
import React from 'react' ; import { PieChart, Pie } from 'recharts' ; const App = () => { // Sample data const data = [ { name: 'Geeksforneveropen' , students: 400 }, { name: 'Technical scripter' , students: 700 }, { name: 'Geek-i-knack' , students: 200 }, { name: 'Geek-o-mania' , students: 1000 } ]; return ( <PieChart width={700} height={700}> <Pie data={data} dataKey= "students" outerRadius={250} innerRadius={150} fill= "green" /> </PieChart> ); } 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/, you will see the following output:
