        Generate PlantUML code for an object diagram based on the following project:

        Project: {project_name}
        Description: {project_description}
        Entities: {entities_classes}

        Instructions:
        1. Show object instances and their relationships
        2. Include attribute values for a specific scenario
        3. Use standard PlantUML object diagram syntax
        4. Don't include any explanation, just the PlantUML code

        Example format (DO NOT TREAT THIS AS VARIABLES):
        '''plantuml
        @startuml
        object "Object1" as o1 {{
          attribute1 = value1
          attribute2 = value2
        }}
        object "Object2" as o2 {{
          attribute3 = value3
        }}
        o1 --> o2 : relationship
