{"version":"1.0","type":"rich","title":"D3_CookBook(v5)_Ch3 pt2","description":"This example demonstrates a streaming bar chart that updates every 1.5 seconds by shifting the first data point and pushing a new random value onto the end of an array. It shows the classic D3 data-join pattern using `.enter()`, `.update`, and `.exit()` to manage div elements with the class `h-bar`. The code uses `d3.select` and `data()` binding to set each bar’s width and display its numeric value in a span. The visualization relies on `setInterval` to trigger re-renders, with the bars growing and shrinking as the dataset evolves.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/12814d2103ae447c88a067afd4c9c0b8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
