{"version":"1.0","type":"rich","title":"Barchart","description":"Five series of smoothly varying data are visualized as a stacked bar chart that toggles between stacked and grouped layouts every two seconds. Using D3 v5, the chart binds stacked data to SVG rectangles and animates transitions with `transition.attr` to interpolate positions and sizes between the two arrangements. Radio buttons let users manually switch layouts, with an interval timer resetting on interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9f149f56f7254c8c93317bad1e488fde?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
