This example demonstrates a simple bar chart constructed from 25 randomly generated rounded values. The visualization uses D3 version 4.5.0, with the code generating a fresh dataset of integers between 0 and 29 and rendering each as a teal vertical bar. The chart employs D3’s `selectAll`, `data`, `enter`, and `append` methods to create div elements, with each bar’s height dynamically set via the `.style` method based on the data value multiplied by five. The animation metadata refers to the random generation process rather than a temporal transition.
