+            
+            The full React dashboard has been built and is available. However, due to Gradio's architecture,
+            we recommend using the **API Access** and **Upload Dataset** tabs below for the best experience on HF Spaces.
+            
+            The React dashboard provides:
+            - Natural language query interface  
+            - Real-time SQL generation and execution
+            - Interactive visualizations
+            - PDF report generation
+            - Dataset management and CSV upload
+            
+            **Note:** For the full React experience, you may want to run this locally or deploy the frontend separately.
