{"version":"1.0","type":"rich","title":"Heart-Shaped Hole","description":"This example shows a solid gray circle with a heart-shaped hole cut out of its center. It uses an SVG `<mask>` element, where a white rectangle reveals the circle and a black heart-shaped `<path>` hides that portion. The heart is drawn using quadratic Bézier curves, and the mask is applied to the circle via the `mask` attribute in inline SVG. The code runs directly in a bare-bones HTML page without any external JavaScript libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db9c3a88ec754a3da824342329401e86?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
