###Instruction: Generate a small python repo for matplotlib to visualize timeseries data to read from timeseries.csv file using polars. 
###Response:  The repository should include the following:
- A `src` directory for the Python source files.
- A `data` directory for the input CSV file.
- A `requirements.txt` file listing the necessary libraries.
- A `README.md` file explaining how to use the tool.
- A `run.sh` script to execute the main program.

Create the repository structure and populate it with the necessary files. ```python
<libs>matplotlib,polars</libs>
<planning>
#1 Create the repository structure.
   - Initialize the git repository.
   - Create the `src`, `data`, and `docs` directories.
#2 Populate the repository with necessary files.
   - Add a `requirements.txt` file with the necessary libraries.
   - Add a `README.md` file explaining how to use the tool.
   - Add a `run.sh` script to execute the main program.
   - Add a Python script in `src` to visualize timeseries data.

# Timeseries Visualization Tool

This tool visualizes timeseries data loaded from a CSV file using `pandas` for data handling and `matplotlib` for plotting.

## Requirements

Ensure you have the following libraries installed:

```bash
pip install -r requirements.txt
```

## Usage

To run the visualization tool, execute the following command:

```bash
bash run.sh
```

## Data

The tool expects a CSV file named `timeseries.csv` in the `data` directory with the following columns:
- `timestamp`: Timestamp of the data point.
- `value`: Value of the timeseries data.
