Removed the inlined `VisualizationRecommender` class from `suggestions.py` and imported it from `visual_suggestion.recommender` - Simplified `suggestions.py` to serve as a lightweight interface for visualization recommendation - Updated `__init__.py` imports to correctly expose `VisualizationRecommender` from its new package - Enhanced `recommender()` function to support: - `StrategyName` parameter for configurable model selection strategy - `selected_models`, `interactive`, and `timeout` arguments for flexible runtime behavior - Improved module clarity and reduced redundancy by centralizing model, API, and ensemble logic under the recommender system --- plotsense/visual_suggestion/__init__.py | 3 +- plotsense/visual_suggestion/suggestions.py | 622 +-------------------- 2 files changed, 21 insertions(+), 604 deletions(-) diff --git a/plotsense/visual_suggestion/__init__.py b/plotsense/visual_suggestion/__init__.py index 9eba1bb..9c9fe01 100644 --- a/plotsense/visual_suggestion/__init__.py +++ b/plotsense/visual_suggestion/__init__.py @@ -1 +1,2 @@ -from plotsense.visual_suggestion.suggestions import recommender, VisualizationRecommender +from plotsense.visual_suggestion.suggestions import recommender +from plotsense.visual_suggestion.recommender import VisualizationRecommender diff --git a/plotsense/visual_suggestion/suggestions.py b/plotsense/visual_suggestion/suggestions.py index 7225fac..62863fa 100644 --- a/plotsense/visual_suggestion/suggestions.py +++ b/plotsense/visual_suggestion/suggestions.py @@ -1,609 +1,12 @@ -import os -from typing import Dict, List, Optional, Tuple, Callable -from collections import defaultdict +from typing import Dict, List, Optional, Tuple from dotenv import load_dotenv import pandas as pd -import numpy as np -import warnings -import concurrent.futures -from concurrent.futures import ThreadPoolExecutor -import textwrap -import builtins -from pprint import pprint -from groq import Groq +from plotsense.core.enums.strategy import StrategyName +from plotsense.visual_suggestion.recommender.visualization_recommender import VisualizationRecommender -load_dotenv() -

If a suggestion includes both numerical and categorical variables, NUMERICAL VARIABLES MUST COME FIRST. - - Correct: "income, gender" - - Incorrect: "gender, income" - 2. For plots requiring two numerical variables (e.g., scatter), order by analysis priority (dependent variable first). - 3. For single-variable plots, use natural order (e.g., "age" for a histogram). - - GENERAL RULES FOR ALL PLOT TYPES: - 1. Ensure the plot type is a valid matplotlib function - 2. The plot type must be appropriate for the variables' data types - 3. The number of variables must match what the plot type requires - 4. Variables must exist in the dataset - 5. Never combine incompatible variables - 6. Always specify complete variable sets - 7.

Ensure the common plot types requirements are met including the data types - - COMMON PLOT TYPE REQUIREMENTS (non-exhaustive): - 1. bar: 1 categorical (x) + 1 numerical (y) → Variables: [numerical], [categorical] - 2. scatter: Exactly 2 numerical → Variables: [independent], [dependent] - 3. hist: Exactly 1 numerical → Variables: [numerical] - 4. boxplot: 1 numerical OR 1 numerical + 1 categorical → Variables: [numerical], [categorical] (if grouped) - 5. pie: Exactly 1 categorical → Variables: [categorical] - 6. line: 1 numerical (y) OR 1 numerical (y) + 1 datetime (x) → Variables: [y], [x] (if applicable) - 7. heatmap: 2 categorical + 1 numerical OR correlation matrix → Variables: [numerical], [categorical], [categorical] - 8. violinplot: Same as boxplot - 9. hexbin: Exactly 2 numerical variables - 10. pairplot: 2+ numerical variables - 11. jointplot: Exactly 2 numerical variables - 12. contour: 2 numerical variables for grid + 1 for values - 13. quiver: 2 numerical variables for grid + 2 for vectors - 14. imshow: 2D array of numerical values - 15. errorbar: 1 numerical (x) + 1 numerical (y) + error values - 16. stackplot: 1 numerical (x) + multiple numerical (y) - 17. stem: 1 numerical (x) + 1 numerical (y) - 18. fill_between: 1 numerical (x) + 2 numerical (y) - 19. pcolormesh: 2D grid of numerical values - 20. polar: Angular and radial coordinates - - If suggesting a plot not listed above, ensure: - - The function exists in matplotlib - - Variable types and counts are explicitly compatible - - The rationale clearly explains the insight provided - - Additional Requirements: - 1. For specialized plots (like quiver, contour), ensure all required components are specified - 2. Consider the statistical properties and relationships of the variables - 3. Suggest plots that would reveal meaningful insights about the data - 4. Include both common and advanced plots when appropriate - - Example CORRECT suggestions (NUMERICAL FIRST): - Plot Type: boxplot - Variables: income, gender - Rationale: Compares income distribution across genders - --- - Plot Type: scatter - Variables: age, income - Rationale: Shows relationship between age and income - --- - Plot Type: bar - Variables: revenue, product_category - Rationale: Compares revenue across product categories - - Example INCORRECT suggestions (REJECT THESE): - Plot Type: boxplot - Variables: gender, income #

initialization and testing of `explainer` and `recommender` modules with consistent `API` handling and helper usage - Added default argument values to `VisualizationRecommender` and `PlotExplainer` constructors for strategy, models, timeout, and interactivity - Introduced `self.api_keys` and standardized `ProviderManager` initialization across both components - Updated `test_explanations` to use shared helper functions `encode_image` and `save_plot_to_image` from `core.utils` - Revised `test_plotgen` to align with new `_default_plots` naming and initialization logic - Refactored `test_suggestions` to leverage new `ResponseParser`, updated recommendation pipeline, and aligned prompt/query flow - Commented deprecated internal tests tied to removed private methods (`_get_all_recommendations`, `_parse_recommendations`, etc.) - Ensured test assertions verify model availability and provider correctness under new recommender structure ---
