## Description

A simple ROS2 node that publishes string messages to the `chatter` topic at a 1 Hz rate. This demonstrates basic publisher functionality with a timer callback in Python.

## Publishers

- **Topic**: `/chatter`
  - **Type**: `example_interfaces/msg/String`
  - **QoS**: Queue size of 10
  - **Description**: Publishes "Hello World" messages with an incrementing counter

## Example Usage

```bash
# Run the talker node
ros2 run demo_nodes_py talker
```

The talker will publish and log messages in the format:
```
[INFO] [talker]: Publishing: "Hello World: 0"
[INFO] [talker]: Publishing: "Hello World: 1"
...
```

To test with a listener:
```bash
# Terminal 1: Run talker
ros2 run demo_nodes_py talker

# Terminal 2: Run listener
ros2 run demo_nodes_py listener
```
