+If `pip` is not recognized as a command, it might be because it is not installed or not added to your system's PATH. Here are steps to address this:
+
+1. **Ensure Python and pip are installed**:
+   - If you are on Windows, you can download the Python installer from [python.org](https://www.python.org/downloads/). During installation, make sure to check the option to "Add Python to PATH".
+   - If you are on macOS or Linux, Python might already be installed. You can check by running `python --version` or `python3 --version` in the terminal.
+
+2. **Installing pip**:
+   - If Python is installed but pip is not, you can install pip manually. Download `get-pip.py` by running:
+     ```bash
+     curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
+     ```
+   - Then run the following command to install pip:
+     ```bash
+     python get-pip.py
+     ```
+
+3. **Using pip3**:
+   - On some systems, especially if both Python 2 and Python 3 are installed, you might need to use `pip3` instead of `pip`. You can install matplotlib using:
+     ```bash
+     pip3 install matplotlib
+     ```
+
+4. **Verify the installation**:
+   - After installing pip, you can verify the installation by running:
+     ```bash
+     pip --version
+     ```
+   - If you had to use `pip3` to install, verify with:
+     ```bash
+     pip3 --version
+     ```
+
+5. **Installing matplotlib with pip**:
+   - Once pip is available, you can install matplotlib by running:
+     ```bash
+     pip install matplotlib
+     ```
+   - Or if you used `pip3`:
+     ```bash
+     pip3 install matplotlib
+     ```
+
+6. **Running the script**:
+   - After installing matplotlib, create the `generate_charts.py` file as described previously, and run it with:
+     ```bash
+     python generate_charts.py
+     ```
+   - Or if you need to use Python 3 explicitly:
+     ```bash
+     python3 generate_charts.py
+     ```
+
+If you run into any specific issues or errors during these steps, please let me know so I can help troubleshoot further.

 ### Instructions to run the script:
 It looks like `pip` was installed in a directory that is not included in your system's PATH. To resolve this, you can add the directory to your PATH temporarily or permanently.
