{"version":"1.0","type":"rich","title":"Web Audio Theremin & Oscilloscope","description":"A Web Audio Theremin lets a user control pitch and volume by moving the mouse vertically and horizontally, with a circular cursor tracking the pointer. An oscilloscope displays the live waveform, while a frequency ticker records recent pitch history as a filled area. The code uses D3 v4 for SVG rendering, transitions, and scales, alongside the Web Audio API's `OscillatorNode`, `GainNode`, and `AnalyserNode` to generate and visualize sound.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-41bf2c3727c59a3366528807c2c708b2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
