This stacked bar chart visualizes survey data on gadget usage, showing how different work statuses (such as Employed and School Student) rate various motivations like "Winning" and "Having Fun." The chart uses d3.layout.stack to layer series representing each motivation, with d3.scale.ordinal and d3.svg.axis handling the x and y axes. SVG rectangles render each segment, and a tooltip displays the average gadget value on mouseover. A legend at the right identifies the series, with data from dataset.csv.
