{"version":"1.0","type":"rich","title":"Untitled","description":"Three bar charts show categorical values for groups A, B, and C, with a button-driven transition between two predefined datasets. Using d3.v4 with React, the visualization renders SVG rectangles that animate their heights and positions over one second via `transition()`. The y-axis scale is fixed from 0 to 20, while the x-axis uses `d3.scaleBand`. Clicking the buttons calls an `update` function that rebinds data and triggers the smooth visual change.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2b7ece60683421ab37c7668f80b3e2f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
