{"version":"1.0","type":"rich","title":"Barchart","description":"This example shows an interactive bar chart with multiple data series that can be toggled between grouped and stacked layouts via radio-button style controls. Additional buttons allow users to show or hide individual series. The visualization uses D3 v6 with SVG rendering and animated transitions, employing `d3.stack` to compute stacked values and `d3.scaleBand` and `d3.scaleLinear` for positioning. Data is generated procedurally using smooth random bumps, and mouseover interactions display tooltips with precise values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7055427dc5614ce0b016e80f3520c943?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
