                Please generate a 2D CAD file in OpenSCAD for umbrella

Creating a detailed 2D design of an umbrella in OpenSCAD involves using basic geometric shapes and transformations. Below is a basic attempt to represent an umbrella in 2D using OpenSCAD code. This design includes a simple representation of the umbrella's canopy and handle.

```openscad
// Umbrella 2D Design

// Function to draw umbrella canopy
module canopy() {
    difference() {
        circle(d=80, $fn=100);
        translate([0,70]) 
            square([160, 60], true);
    }
}

// Function to draw umbrella handle
module handle() {
    translate([0, -100])
        rotate(90)
            rectangle = rrect([10, 150], 5, 100); // Rounded Rectangle Function Doesn't Exist By Default
}

module rrect(size, radius, round_points) {
    if (round_points) {
        minkowski() {
            circle(r=radius, $fn=round_points);
            square(size-2*[radius, radius], true);
        }
    } else {
        difference() {
            square(size, true);
            translate([-size/2 + radius, -size/2 + radius]) 
                square(size-2*[radius, radius], true);
        }
    }
}

// Draw the umbrella
module umbrella() {
    // Draw the handle
    handle();
    // Draw the canopy
    translate([0, 50])
        canopy();
}

umbrella();
```

### Explanation:
1. **Canopy Module**: The `canopy()` module creates a circle and subtracts a rectangle at the bottom to create a basic umbrella shape.
2. **Handle Module**: The `handle()` module uses a custom-defined rounded rectangle to create the umbrella handle.
3. **Rounded Rectangle Module**: Defined as `rrect()`. It uses Minkowski sum to create a rounded rectangle.
4. **Umbrella Module**: This module combines the `handle()` and `canopy()` to form the overall 2D umbrella.

To run this, you can copy and paste the code into the OpenSCAD editor and render it. This script creates a simplified representation of a 2D umbrella. You can customize dimensions and details further as required for your project.
