A pie chart is a circular chart that is divided into slices to illustrate numerical proportion.

JavaFX PieChart Example

The example uses a pie chart to show the market share of web servers:
package sample;

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Scene;
import javafx.scene.chart.PieChart;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;

public class Main extends Application {

    public void start(Stage stage) {


    private void initUI(Stage stage) {

        HBox root = new HBox();

        Scene scene = new Scene(root, 450, 330);

        ObservableList<PieChart.Data> pieChartData
                = FXCollections.observableArrayList(
                new PieChart.Data("Apache", 52),
                new PieChart.Data("Nginx", 31),
                new PieChart.Data("IIS", 12),
                new PieChart.Data("LiteSpeed", 2),
                new PieChart.Data("Google server", 1),
                new PieChart.Data("Others", 2));

        PieChart pieChart = new PieChart(pieChartData);
        pieChart.setTitle("Web servers market share (2022)");



    public static void main(String[] args) {
