Bugle Charts
Bugle charts display hierarchical distributions across multiple groups and years, with each cell containing a vertical axis where colored shapes show prior, actual, and expected values as trapezoids with animated transitions. The visualization includes a "Randomize" button that regenerates the underlying data, triggering smooth SVG transitions via d3.js v3. Rendered with SVG elements and ordinal/linear scales, the chart uses d3.svg.axis for axes, d3.svg.line for path outlines, and a dashed line to represent totals. Each group's cell is positioned using d3.scale.ordinal for x and y coordinates, with y2 scales dynamically adjusting to variance ranges.
