{"version":"1.0","type":"rich","title":"d3 tutorial","description":"A tutorial demonstrates basic D3.js selection and DOM manipulation using a static HTML page with car listings and paragraphs. The code uses `d3.select` and `d3.selectAll` to change text colors—turning headings blue, list items magenta, and paragraphs green—and to style nested table cells with cyan backgrounds. Data binding via `.data()` maps an array of numbers to blank `h2` elements, while class-based selectors color warning and error messages. All styling is applied through D3's `.style()` and `.text()` methods on the live DOM.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6eb0b6decfce4016802eab0ec47ed060?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
