In this example, enter following prompts for generate web application from zero.

To create a 3D Google Earth, you need to load the terrain map correctly. You can use any online resource. The code is written into an HTML file.
Now it will start generating new codes and having similar to following screenshot:
To validate if earlier Qwen3-Coder generated output codes are really working fine, we proceed to copy whole codes and test on separate website.
Paste whole codes into Real-time HTML Editor via https://htmledit.squarefree.com/. (Notes: You may choose any other preferred HTML editor)
It should able to display 3D Terrain Visualization web application, similar to following screenshot:
Done! You have just successfully vide coded new web application using Qwen3 LLM model, and good to proceed with any new prompts based on your preferences.
