GH audio-responsive circular patterns not visible in Rhino

I’m creating an audio-responsive art generator using Grasshopper and C#. The script generates circular patterns that should change based on audio input (volume, frequency, and rhythm). The output is intended for web display.

The Grasshopper script runs without errors, but no geometry is visible in the Rhino viewport.
The C# script output (connected to a Panel) shows no data. I’ve double-checked all connections and input values. Despite troubleshooting, including simplifying the script, the Rhino viewport remains empty.

Any assistance in identifying why the geometry isn’t appearing would be greatly appreciated.
