{"version":"1.0","type":"rich","title":"Fork of Rainbow Piano","description":"This interactive visualization presents a two-octave piano keyboard rendered in SVG, with each white key colored in a distinct pastel rainbow hue. Users click individual keys to trigger a short synthesized sine wave tone, created through the Web Audio API's `createOscillator` and `createGain` nodes. Pressed keys temporarily darken via CSS transitions and React's `useState`, visually confirming the note selection. The layout maps 24 notes (C1 through B2) to specific frequencies, displaying numeric solfège labels on each key.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/67d0f4f0eec3464f98ec782f9cf7250b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
