The Product Schema Markup Generator

Act as a structured data specialist. Help me generate the JSON-LD code for Product schema to enhance the product listing in search results with rich snippets.

• Product Name: [e.g., "Model X Smartwatch"]
• Brand: [e.g., "TechBrand"]
• Image URL: [e.g., "https://example.com/image.jpg"]
• Description: [e.g., "A premium smartwatch for fitness and health tracking."]
• SKU: [e.g., "SMW-X-2024"]
• Aggregate Rating: [e.g., "4.7"]
• Review Count: [e.g., "142"]

Task: Write the complete JSON-LD script for the Product schema type, including the required properties (name, image, description) and the recommended properties (brand, sku, aggregateRating, reviewCount).
