                Please generate a 2D CAD file in OpenSCAD for flower

Creating a flower in OpenSCAD involves placing the correct shapes and adjusting their parameters to get the right look. Below is a basic example of how to create a simple 2D flower with petals and a center. You can copy and paste this code into OpenSCAD to view and further customize the design.

```openscad
// Function to create a petal shape
module petal(length, width, angle) {
    rotate(angle) {
        ellipse(a=width, b=length);
    }
}

// Function to create an ellipse (as OpenSCAD doesn't have a built-in ellipse function)
module ellipse(a, b) {
    scale([a, b])
        circle(1);
}

// Main flower module
module flower(petal_length=15, petal_width=6, num_petals=6, center_radius=5) {
    for (i = [0:num_petals-1]) {
        petal(petal_length, petal_width, i * 360 / num_petals);
    }
    // Center of the flower
    circle(r = center_radius);
}

// Create the flower
flower();
```

### Explanation:
1. **Petal Module**: 
   - `petal(length, width, angle)`: Creates a petal at a given angle. It uses an `ellipse` module to generate an ellipse for the petal shape.

2. **Ellipse Module**:
   - `ellipse(a, b)`: A helper module to create an ellipse by scaling a circle. Here `a` and `b` are the semi-major and semi-minor axes of the ellipse respectively.

3. **Flower Module**:
   - `flower(petal_length, petal_width, num_petals, center_radius)`: This module uses a loop to create multiple petals around a circle and places a central circle.

4. **Create the Flower**:
   - The last line `flower()` calls the flower module with default parameters to generate the flower.

You can adjust the parameters (`petal_length`, `petal_width`, `num_petals`, `center_radius`) to customize the shape of your flower. Simply copy this code, paste it into OpenSCAD, and render it (`F5`) to see your design. Save your file as `.scad` if you need to keep it for future editing or sharing.
