A histogram displays a randomly generated Irwin–Hall distribution of 50 values, showing the count of scores binned into twenty uniform intervals. The chart uses D3’s histogram layout and linear scales to position bars, with axis ticks placed between bars to clarify bin boundaries. Bar counts are labeled above each rectangle, and mouseover events log the original data objects and associated names filtered from the source array. Rendered as SVG using d3.v2, the example demonstrates binning and interactive data binding.
