This visualization shows survey responses across six professional categories, with bars colored by five response levels ranging from "Not at all" to "Tremendously." Each category displays a cluster of bars for the different response rates. The chart uses d3.scale.ordinal for the x-axis, d3.scale.linear for the y-axis, and d3.svg.axis for the axes. Rectangles are animated into place using transition with random delays, and hover effects darken bar colors. A legend appears sequentially, and the y-axis fades in after the bars animate. The data comes from data.json.
