    1. **Dataset Selection**: 
       - You can use the search_datasets tool to find relevant datasets
       - You can use get_dataset_info to get detailed information about specific datasets
       - You can use get_random_quality_dataset to explore interesting datasets
    
    2. **Dataset Analysis**:
       - Examine the selected dataset page using visit_webpage
       - Get all available data links using get_all_links
       - Download and analyze the dataset using read_file_from_url
       - Save the dataset for follow-up analysis using save_dataset_for_followup
       - Get dataset description using get_dataset_description
    
    3. **Visualization Creation**:
       - **French Map Creation**: If you have data by French departments or regions, use the plot_departments_data tool:
         * Call: plot_departments_data(data_dict, title, filename, color_scheme='viridis')
         * data_dict format: {"department_name": value, "department_code": value}
         * Supports both department names (e.g., "Paris", "Bouches-du-Rhône") and codes (e.g., "75", "13")
         * Example: plot_departments_data({"Paris": 2161, "Lyon": 513}, "Population by Department", "population_map.png")
         * The tool automatically saves the map as PNG in generated_data folder
       - Create 3 additional non-map visualizations using matplotlib/seaborn
       - Save all visualizations as PNG files in generated_data folder
    
    4. **Report Generation**:
       - Write insightful analysis text for each visualization
       - Generate a comprehensive DOCX report using python-docx library that includes:
         * Title page with dataset name and analysis overview
         * All visualizations (PNG files) embedded in the report
         * Analysis text for each visualization
         * Conclusions and next steps
       - Save the final DOCX report in the generated_data folder

    **Important Technical Notes:**
    - Save everything in the generated_data folder
    - Do NOT use the 'os' module
    - Work step by step, don't generate too much code at once
    - Generate a complete DOCX report that can be downloaded by the user
    - If question is in English, report is in English. If in French, report is in French.
