{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"Built with vanilla JavaScript, the example shows a 15-by-15 interactive crossword puzzle with clickable white cells, blocked black cells, and numbered clue lists for Across and Down entries. The `Crossword` class constructs the grid as a DOM grid of `div` and `input` elements, populating letter positions from a small hardcoded word list. Event listeners handle cell focus and letter input, while the CSS applies the layout and puzzle styling. The implementation uses standard DOM APIs such as `document.createElement` and `addEventListener` to manage interaction without external libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b9e1c76fe6e4408fb7e09ee887e5e264?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
