 """Custom Visualizer Example
 
 This example demonstrates how to create and use a custom visualizer by subclassing
-ConversationVisualizer. This approach provides:
+ConversationVisualizerBase. This approach provides:
 - Clean, testable code with class-based state management
 - Direct configuration (just pass the visualizer instance to visualizer parameter)
 - Reusable visualizer that can be shared across conversations
 
-This demonstrates how you can pass a ConversationVisualizer instance directly
+The SimpleVisualizer produces concise output showing:
+- LLM call completions with latency information
+- Tool execution steps with command/path details
+- Error messages
+
+This demonstrates how you can pass a ConversationVisualizerBase instance directly
 to the visualizer parameter for clean, reusable visualization logic.

+      (always added, has response_id)

+    2. Costs may be skipped if zero, so indices don't align perfectly
