{"version":"1.0","type":"rich","title":"D3 Charts","description":"This example presents several D3 chart types—an animated bar chart, a grouped bar chart with a legend, and a stacked bar chart—with controls for interacting with the data. The animated bar chart uses a D3 module pattern with a reusable `barGraph` function, including scale bands, grid lines, transitions, and sorting capabilities. The grouped and stacked bar charts use D3’s `.stack()` and `.scaleBand()` to display categorical data from a CSV file, with each subgroup assigned a distinct color. The visuals are rendered in SVG and canvas, and the graph modules are composed in a single HTML document with a menu for switching between chart views.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
