ADDING NEW ANALYSIS TASKS:
==========================

1. Add task configuration in TaskRegistry.get_config():
   "Your Data Type": {
       "Your Task Name": TaskConfig(
           name="Your Task Name",
           data_type="Your Data Type",
           requires_params=True,  # Set to True if needs parameters
           param_components=[...],  # Define parameter types
           output_tabs=["original", "summary", ...]  # Which tabs to show
       )
   }

2. Add execution method in AnalysisExecutor:
   @staticmethod
   def execute_your_task(df, param1, param2):
       # Your analysis logic
       return "βœ“ Done", {
           "original": df,
           "summary": summary_data,
           ...
       }

3. In create_interface(), add parameter group in the LEFT panel:
   with gr.Group(visible=False) as your_task_param_group:
       gr.Markdown("**Your Task Parameters**")
       your_param1 = gr.Slider(minimum=0, maximum=1, label="Threshold")
       your_param2 = gr.Dropdown(choices=["A", "B"], label="Option")

4. In UIManager.on_tasks_change()

"""
ADDING NEW ANALYSIS TASKS:
==========================

1. Add task configuration in TaskRegistry:
   - Define name, data_type, requires_params, param_components, output_tabs

2. Add execution method in AnalysisExecutor:
   - Create execute_your_task() method
   - Return (status_message, results_dict)

3. Add condition in UIManager.process_analysis():
   - elif task_name == "Your Task Name":
   -     status_msg, results = executor.execute_your_task(df, params)
   -     return self._format_results(status_msg, config.output_tabs, results)


EXAMPLE - Adding a new ECG task with parameters:
================================================

In TaskRegistry.get_config():
    "ECG Data": {
        ...
        "ECG Quality Check": TaskConfig(
            name="ECG Quality Check",
            data_type="ECG Data",
            requires_params=True,
            param_components=[
                {"type": "slider", "label": "Quality Threshold", "elem_id": "quality_thresh"}
            ],
            output_tabs=["original", "summary", "visualization"]
        )
    }

In AnalysisExecutor:
    @staticmethod
    def execute_ecg_quality_check(df: pd.DataFrame, threshold: float) -> Tuple[str, Dict[str, Any]]:
        # Your analysis logic here
        return "βœ“ Quality check completed", {
            "original": df,
            "summary": quality_summary,
            "visualization": viz_html
        }

In UIManager.process_analysis():
    elif task_name == "ECG Quality Check":
        status_msg, results = executor.execute_ecg_quality_check(df, float(param_value))
        return self._format_results(status_msg, config.output_tabs, results)


The architecture is now:
- Simple and clean
- Easy to extend with new tasks
- Dynamic UI based on task configuration
- Fixed chat scrolling issue
