+  2. Clean data and handle missing values
+  3. Perform statistical analysis based on data type
+  4. Generate appropriate visualizations
+  5. Compile comprehensive reports
+
+  Use sub-recipes for specialized tasks and coordinate their execution based on data characteristics.
+  Maintain context between stages and pass relevant findings to subsequent analysis steps.

+
+prompt: |
+  Analyze {{ data_file }} with {{ analysis_type }} mode. Output to {{ output_dir }}.
+
+  CRITICAL: Handle file paths correctly for all operating systems.
+  - Detect the operating system (Windows/Linux/Mac)
+  - Use appropriate path separators (/ for Unix, \\ for Windows)
+  - Be careful to avoid escaping of slash or backslash characters
+  - Use os.path.join() or pathlib.Path for cross-platform paths
+  - Create output directories if they don't exist
+
+  Workflow:
+  1. Validate: Run data_validator subrecipe on {{ data_file }}
+     - Store validation results in memory
+     - Check for critical issues before proceeding
+
+  2. Clean: If issues found, run data_cleaner subrecipe
+     - Pass validation results to cleaner
+     - Handle cleaning errors gracefully
+
+  {% if analysis_type == "statistical" or analysis_type == "comprehensive" %}
+  3. Analyze: Run statistical_analyzer for stats and correlations
+     - Use cleaned data if available
+     - Store analysis results in memory
+  {% endif %}
+
+  {% if include_visualizations == "true" %}
+  4. Visualize: Run chart_generator for key charts
+     - Create output directory structure
+     - Handle visualization errors
+  {% endif %}
+
+  5. Report: Create brief {{ report_format }} summary
+     - Save to {{ output_dir }}/report.{{ report_format }}
+     - Use OS-compatible path construction
+
+  Error Recovery:
+  - If a sub-recipe fails, continue with remaining stages if possible
+  - Log errors clearly with stage information
+  - Provide partial results if complete analysis fails
+
+  For {{ analysis_type }}=="quick", skip heavy computations. Be efficient.
+  Use memory extension to pass results between stages.
+  Always verify paths work on the current OS before file operations.

+    description: For creating and saving visualizations
+
+prompt: |
+  Create simple, clear visualizations for {{ data_file }}.
+  Style: {{ chart_style }}, Colors: {{ color_scheme }}
+
+  Important: Handle file paths correctly for all operating systems.
+  Use os.path.join() or pathlib for directory creation.
+  Detect OS for proper path separators.
+
+  Quick viz workflow:
+  1. Load data with pandas
+  2. Create visualizations directory if not exists
+  3. Create 2-3 essential charts:
+     - Histogram for numerical columns
+     - Bar chart for categorical columns
+     - Correlation heatmap if multiple numeric columns
+  4. Save as PNG to ./visualizations/ with OS-compatible paths
+
+  Error handling:
+  - Create output directory if missing
+  - Handle matplotlib backend issues
+  - Skip charts if data insufficient
+  - Report any visualization errors
+
+  Use matplotlib or seaborn. Keep it simple and fast.
+
+  3. Visualization Standards
+     Apply these best practices:
+     - Clear, descriptive titles
+     - Labeled axes with units
+     - Legends when multiple series
+     - Grid lines for readability (subtle)
+     - Appropriate aspect ratios
+     - Consistent color usage
+     - Annotations for key insights
+
+  4. Style Application
+     {% if chart_style == "modern" %}
+     - Clean, minimalist design
+     - Sans-serif fonts
+     - Subtle grid lines
+     - High contrast colors
+     - White/light backgrounds
+     {% elif chart_style == "classic" %}
+     - Traditional academic style
+     - Serif fonts
+     - Visible grid lines
+     - Conservative colors
+     - Formal layout
+     {% elif chart_style == "minimal" %}
+     - Absolute minimum decoration
+     - No grid lines
+     - Simple colors
+     - Maximum data-ink ratio
+     {% elif chart_style == "publication" %}
+     - Journal-ready formatting
+     - High DPI
+     - Grayscale-safe colors
+     - Clear for print
+     {% endif %}
+
+  5. Interactive Features (if enabled)
+     {% if interactive == "true" %}
+     Create interactive HTML visualizations with:
+     - Hover tooltips showing exact values
+     - Zoom and pan capabilities
+     - Toggle legend items
+     - Download buttons
+     - Responsive layout
+     Use Plotly or Bokeh for interactivity.
+     {% endif %}
+
+  6. Chart Gallery Generation
+     Create the following visualization set:
+
+     A. Distribution Analysis (for each numerical column)
+        - Histogram with KDE overlay
+        - Box plot
+        - Q-Q plot for normality
+
+     B. Relationship Analysis
+        - Correlation heatmap (if multiple numerical columns)
+        - Scatter plots for top correlated pairs
+        - Pair plot matrix
+
+     C. Category Analysis (if categorical data exists)
+        - Bar charts for categorical frequencies
+        - Grouped bar charts for relationships
+        - Proportional visualizations
+
+     D. Time Series (if temporal data exists)
+        - Line plots with trend lines
+        - Seasonal decomposition
+        - Moving averages
+
+     E. Overview Dashboard
+        - Combined multi-panel figure
+        - Key metrics summary
+        - Highlight important patterns
+
+  7. Save Visualizations
+     - Save each chart with descriptive filename
+     - Use {{ output_format }} format
+     - Organize in subdirectories by type
+     - Create index.html gallery if interactive
+     - Generate thumbnail versions
+
+  8. Visualization Report
+     Create a summary document with:
+     - List of all generated visualizations
+     - Description of each chart
+     - Key insights visible in each viz
+     - Recommendations for interpretation
+     - Technical notes (libraries, settings used)
+
+  Focus on clarity and insight communication over decorative elements.
+  Ensure all visualizations are self-explanatory and publication-ready.
