This bar chart visualizes sleep duration for individuals, with each bar representing a person’s name and the bar height corresponding to their hours of sleep. The visualization uses d3.csv to load data from a remote ICE5dataset, d3.scaleBand for the x-axis categories, and d3.scaleLinear for the y-axis. Bars are rendered as SVG rectangles with a hover effect that changes their fill to orange via d3.select, while d3.axisBottom and d3.axisLeft generate the labeled axes.
