     """
-    SmartScraper is a comprehensive web scraping tool that automates the process of extracting
-    information from web pages using a natural language model to interpret and answer prompts.
+    A class representing a graph for extracting information from CSV files.
+
+    Attributes:
+        prompt (str): The prompt used to generate an answer.
+        source (str): The source of the data, which can be either a CSV 
+        file or a directory containing multiple CSV files.
+        config (dict): Additional configuration parameters needed by some nodes in the graph.
+
+    Methods:
+        __init__ (prompt: str, source: str, config: dict, schema: Optional[BaseModel] = None):
+            Initializes the CSVScraperGraph with a prompt, source, and configuration.
+
+        __init__ initializes the CSVScraperGraph class. It requires the user's prompt as input, 
+            along with the source of the data (which can be either a single CSV file or a directory 
+            containing multiple CSV files), and any necessary configuration parameters.
+
+    Methods:
+        _create_graph (): Creates the graph of nodes representing the workflow for web scraping.
+
+        _create_graph generates the web scraping process workflow 
+            represented by a directed acyclic graph. 
+            This method is used internally to create the scraping pipeline 
+            without having to execute it immediately. The result is a BaseGraph instance 
+            containing nodes that fetch and process data from a source, and other helper functions.
+
+    Methods:
+        run () -> str: Executes the web scraping process and returns 
+            the answer to the prompt as a string.
+        run runs the CSVScraperGraph class to extract information from a CSV file based 
+            on the user's prompt. It requires no additional arguments since all necessary data 
+            is stored within the class instance. The method fetches the relevant chunks of text or speech,
+            generates an answer based on these chunks, and returns this answer as a string.
