This histogram visualizes the frequency distribution of byte values from a data source, binning values into 16-unit intervals from 0 to 255. The code uses d3.histogram to create bins and d3.scaleLinear for both x and y axes, rendering bars as SVG rectangles. The chart includes labeled axes for byte value (in hex) and frequency, with light green bars matching the specified styling. The sample data contains repeated byte values like 0x00 and 0xf8, demonstrating how the histogram groups and counts occurrences across the full byte range.
