{"version":"1.0","type":"rich","title":" Rainbow Piano App","description":"Rainbow Piano App is an interactive virtual piano that generates musical tones through a Web Audio API, playable via mouse clicks, touch events, or computer keyboard mappings. The visualization presents a gradient-styled keyboard with animated key presses, where white keys respond to letter keys A through semicolon and black keys map to W, E, T, Y, U, O, and P. A demo melody button triggers a pre-recorded sequence. The interface uses DOM manipulation with CSS transitions for a smooth, responsive design across different screen sizes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a0c0ac4211b4bed8c7b10a8997af263?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
