      lowerfence: [-2.5],
      upperfence: [2.7],
      name: 'X',
      boxpoints: false
  };
  const data = Array.from({ length: 500 }, () => (Math.random() - 0.5) * 4);
  const violin = {
      type: 'violin',
      y: data,
      box: { visible: true },
      meanline: { visible: true },
      name: 'X'
  };
  
  Plotly.newPlot(gd, [box]).then(() => Plotly.react(gd, [violin]));
