Pyramid Pie
A pyramid pie chart uses a single D3 pie layout to show proportions as a rotated, triangular arrangement of three slices: sky, sunny side, and shady side. The chart uses `d3.layout.pie` and `d3.svg.arc` to compute slice geometry, and `d3.legend` to render a circular legend. Colors are assigned via an ordinal scale, and the whole pie is rotated with a transform. Data comes from a CSV file with feature, label, and proportion columns.
