     Generates a Process Flow Diagram (Flowchart) from JSON input.
 
     Args:
         json_input (str): A JSON string describing the process flow structure.
                           It must follow the Expected JSON Format Example below.
-        base_color (str): The hexadecimal color string (e.g., '#19191a') for the base
-                          color of the nodes, from which a gradient will be generated.
 
     Returns:
         str: The filepath to the generated PNG image file.
