Documentation

This package provides a variety of shape generators for your convenience. As with other aspects of D4, these shapes are driven by data: each shape generator exposes accessors that control how the input data are mapped to a visual representation.

See one of:

• Arcs - circular or annular sectors, as in a pie or donut chart.
• Areas - an area defined by a bounding topline and baseline, as in an area chart.
• Curves - interpolate between points to produce a continuous shape.
• Lines - a spline or polyline, as in a line chart.
• Links - a smooth cubic Bézier curve from a source to a target.
• Pies - compute angles for a pie or donut chart.
• Stacks - stack adjacent shapes, as in a stacked bar chart.
• Symbols - a categorical shape encoding, as in a scatterplot.
• Radial areas - like area, but in polar coordinates.
• Radial lines - like line, but in polar coordinates.
• Radial links - like link, but in polar coordinates.
