    Your task is to generate a comprehensive market analysis report in HTML format.

    **Instructions:**
    1.  Write a full HTML document.
    2.  Use the provided "Market Trends" text to write the main body of the report. Structure it with clear headings and paragraphs.
    3.  Incorporate the provided "Chart Configurations" to visualize the data. For each chart, you MUST create a unique <canvas> element and a corresponding <script> block to render it using Chart.js.
    4.  Reference the "Sources" at the end of the report.
    5.  Do not include any placeholder data; use only the information provided.
    6.  Return only the raw HTML code.

    **Chart Rendering Snippet:**
    Include this script in the head of the HTML: <script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
    For each chart, use a structure like below, ensuring the canvas 'id' is unique for each chart, and apply the correspinding config:

    ---
    <div style="width: 800px; height: 600px;">
      <canvas id="chart1"></canvas>
    </div>
    <script>
      new Chart(document.getElementById('chart1'), config);
    </script>
    ---
    (For the second chart, use 'chart2' and the corresponding config, and so on.)

    **Data:**
    - Market Trends: ${marketTrends}
    - Chart Configurations: ${JSON.stringify(chartConfigs)}
    - Sources: ${JSON.stringify(sources)}
    `,
  });

  // LLMs may wrap the HTML in a markdown code block, so strip it.
  const finalHtml = htmlReport.replace(/^```html\n/, "").replace(/\n```$/, "");

  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.setContent(finalHtml);
  await page.pdf({ path: "report.pdf", format: "A4" });
  await browser.close();

  console.log("\nReport generated successfully: report.pdf");
