{"version":"1.0","type":"rich","title":"Piano App","description":"An interactive virtual piano with white and black keys generates musical tones through the Web Audio API, allowing play via mouse, touch, or keyboard. The instrument displays a realistic 3D design using CSS gradients and shadows, with visual feedback through CSS transitions on key presses. A built-in demo melody button triggers a pre-programmed scale. The implementation dynamically creates piano keys through DOM manipulation and uses Web Audio API for audio synthesis with gain control, demonstrating front-end techniques for responsive instrument interfaces.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8761492784824563a47231491755f8dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
