-To give you the complete, updated code that includes the visualization feature, I will first verify the most current and stable model names for Google Gemini, as the previous attempts resulted in a `404` error due to model naming changes. This will ensure the final code is functional and accurate.
+The syntax error you're encountering, `SyntaxError: unterminated string literal`, means there's an issue with how a string is defined in your Python code. The Python interpreter detected a string that was started but never properly closed.
 
-Here are the queries I'll use:
-Based on the search results, the following are the latest stable Google Gemini model names for the `v1beta` API:
+This is happening because the AI, in a previous response, included a comment block that contained a line like `Here are the queries I'll use:`. This line was not a valid Python comment or string and was incorrectly inserted at the top of the Python file, causing the syntax error.
 
-  * `gemini-2.5-pro`
-  * `gemini-2.5-flash`
-  * `gemini-2.5-flash-lite`
-  * `gemini-2.0-flash-001`
-  * `gemini-2.0-flash-lite-001`
+To fix this, you need to remove the invalid text from the top of your `app.py` file and ensure the code starts with the standard Python shebang and docstring. The file should begin with the line `#!/usr/bin/env python3` and the code block provided in the previous, corrected response.
 
-The `gr.Mermaid` component is a valid Gradio component for rendering Mermaid diagrams.

-Here is the complete, updated code. I have made the necessary changes to integrate the `gr.Mermaid` component and use a more current, stable model name to avoid the `404` error.
+### Corrected Code
+
+Below is the complete, correct Python code. Simply copy and paste this entire block into your `app.py` file, replacing all its current contents. This will remove the syntax error and ensure the application runs as intended.
