{"version":"1.0","type":"rich","title":"MasteringD3js_ReuseProD3_Ch2 pt2.2dii","description":"This example demonstrates a reusable barcode chart pattern using D3.js version 5, showing how to add and remove data through button interactions. The visualization generates random date intervals using an exponential distribution function, then displays the temporal data as vertical bars within an SVG container. The code implements a modular chart structure with separated concerns for building scales, SVG elements, and rendering the barcode, using d3.scaleTime for time-based positioning and d3.max/d3.min for domain calculations. The example highlights the transition from D3 v3 to v5 while following the ProD3.js reusable chart pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e80d561d6eef43999a755998a66aa64c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
