A dynamic bar chart displays ten data values as vertical bars with numeric labels. Users can click a text prompt to trigger a one-time update to a new dataset. The chart uses D3.js version 4.5.0 with `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and `transition().delay()` to create a staggered animation effect. As the data updates, both the rectangle heights and label positions animate sequentially, with fill colors shifting from dark to light blue based on the new values.
