This radial stacked bar chart displays the distribution of sample counts across seven age groups for four data quality categories. The visualization uses a circular layout with age groups placed around the circumference, while stacked segments radiate outward to represent proportional counts within each category. The code leverages d3.scaleBand for angular positioning, a custom d3.scaleRadial() for radial scaling, and d3.arc() to generate the annular segments. Data comes from a CSV file, and the rendering is done via SVG elements.
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!
