{"version":"1.0","type":"rich","title":"56. D3 Duration","description":"A bar chart displays twenty data values as vertically oriented rectangles, each labeled with its numeric value. Clicking the prompt text triggers a one-time update with a new dataset. The visualization uses D3 v4.5.0 to construct an SVG scene with `d3.scaleBand` for x-axis positioning and `d3.scaleLinear` for bar heights. The update applies a `transition` with a controlled `duration` of 1000 milliseconds, smoothly animating the rectangles' y-coordinates, heights, and fill colors. Text labels update instantly without transition.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/51976cbdaed047b9943f0758f8711c03?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
