{"version":"1.0","type":"rich","title":"htmldiff","description":"htmldiff visualizes changes between two HTML documents by rendering the before and after versions side-by-side with matching content highlighted. It uses a custom tokenizer to split HTML into tags, words, and whitespace, then applies a diff algorithm that finds matching blocks and computes insertions, deletions, and replacements. The result is displayed through a renderer that wraps changed segments with styled spans, making edits immediately visible. The code relies on plain JavaScript DOM manipulation and CSS classes rather than external visualization libraries.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-b47899a9cbe7764e35088837ff2a79ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
