Radial Stacked Bar
A radial stacked bar chart displays population distributions across U.S. states, segmented by seven age groups. The SVG rendering uses d3.stack for data transformation and d3.arc to draw annular segments, with d3.scaleBand for angular positioning and the custom d3-scale-radial.js library (scaleRadial) for radial distances. Data comes from a CSV file, and colors are assigned via d3.scaleOrdinal. The circular layout emphasizes cyclical patterns, though the code notes this form is gratuitous for this non-cyclical dataset.
AI-generated descriptionThis is a radial variant of my earlier example stacked bar chart. While pretty, you probably don’t want to use this version because it’s easier to compare the bars when they share an aligned (linear) axis. You might consider this form if your ordinal axis is cyclical, such as weeks of the year, and you want to show a cyclical pattern. This example’s data is not cyclical, so the use of a radial form here is rather gratuitous!
