fetch('information.json')
  .then(response => response.json())
  .then(information => 
    // Your Chart.js code right here, utilizing the fetched information
  );

// Or utilizing async/await:
async perform createChart() 
  const information = await fetch('information.json').then(response => response.json());
  // Your Chart.js code right here, utilizing the fetched information

createChart();
