{"version":"1.0","type":"rich","title":"67. D3 Randomized Data","description":"A bar chart displays 20 vertical bars whose heights and blue color intensities correspond to values in a static array. Clicking the text prompt replaces the dataset with 20 new random integers between 0 and 24, then animates the bars and their value labels using `transition` with `delay` and `duration`. The chart uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with SVG `rect` and `text` elements. Data is updated via a click handler on a paragraph element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1006ebf295f249f595f232c31870712e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
