Create an ER model for the following mini-world description:

A retail store wants to develop a database system to manage its inventory, which includes various types of products. All products have a unique Product ID, name, price, and quantity in stock. Products are categorized into three types: Electronics, Clothing, and Groceries. Electronic products have attributes such as brand, model, and warranty period (in months). Some electronics products may also have specifications like screen size, RAM, and storage capacity. Clothing products have attributes such as size, color, and fabric. Some clothing products may also have a style (e.g., formal, casual) and gender (e.g., men's, women's). Grocery products have attributes like expiration date, manufacturer, and weight (in grams). Some grocery products may also have nutritional information, such as calories and ingredients. The store has various suppliers who provide products. Each supplier has a unique Supplier ID, name, contact information (phone and email), and address. The store places orders with suppliers to replenish its inventory. Each order has a unique Order ID, order date, and total cost. Orders contain multiple products, and for each product in the order, the quantity and cost are recorded.
