This example demonstrates a dynamic bar chart that updates its data through a sequence of timed transitions. Initially, the chart renders 51 randomly generated values as vertical bars using D3 v5’s `scaleBand` and `scaleLinear` for positioning. After one second, the data array is shuffled in place, triggering a smooth transition that reorders the bars. One second later, the final data point is removed, and the exiting bar animates its height to zero before being removed from the SVG. The visualization showcases D3’s data-join pattern with `selection.merge` and `transition.attr` for animated updates.
