Description:

d4 shape

d4_shape


Graphical primitives for visualization, such as lines and areas.















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.
