A radial stacked bar chart displays state population by age group around a circular axis. Each state's total population extends outward from the center, with colored segments stacked to represent age brackets. The chart uses d3.stack, d3.scaleBand, d3.scaleRadial, and d3.arc for rendering SVG paths. Data comes from a CSV file, with population values shown on circular gridlines. A legend identifies the seven age categories.

AI-generated description

This 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!

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.

Radial Stacked Bar

This radial stacked bar chart displays the age distribution of each U.S. state’s population as concentric arcs. The visualization uses a d3.radial scale to map population totals from the inner to outer radius, while d3.stack and d3.arc render the stacked segments between angular bands. State labels rotate around the circle, and circular gridlines mark population tick values. The data comes from a CSV file, rendered as SVG using D3 v4.

Stacked Radial Bar Chart example.

This stacked radial bar chart displays the population distribution across seven age groups for each U.S. state, using concentric rings to encode values. The chart is rendered as SVG with D3 v7, using `d3.scaleBand` for angular positioning, `d3.scaleRadial` for radial distances, and `d3.stack` to create the layered segments. Color is assigned via `d3.scaleOrdinal`, with helpers for axis labels and a legend. Data comes from a CSV file with state-level census figures.

Radial Stacked Bar III

A radial stacked bar chart displays the population distribution of U.S. states across seven age groups from the provided CSV data. The visualization arranges states as sectors around a center, with each sector subdivided into colored segments representing age categories. Labels rotate around the circumference, and circular grid lines with tick labels indicate population values. The code uses a custom `d3.scaleRadial` extension built on `d3-scale`, combined with `d3.scaleBand`, `d3.stack`, and `d3.arc` to render SVG paths. A weaving algorithm reorders states to improve label legibility.

Radial Stacked Bar III

This radial stacked bar chart shows the population distribution of US states across seven age brackets, with each state occupying a wedge and segments representing age groups. The arcs are drawn with D3’s `d3.arc()` using `innerRadius` and `outerRadius` from a custom `d3.scaleRadial()` (defined in `d3-scale-radial.js`), with data loaded from `data.csv`. State labels rotate around the plot, and grid circles with tick labels mark population totals. A legend identifies the age categories, while the `weave()` function reorders states by the 65+ population.

Radial Stacked Bar

A radial stacked bar chart displays population distribution across U.S. counties by age bracket, arranged around a circular axis to emphasize potential cyclical patterns, though the data is not cyclical. The visualization uses D3 v4 with a custom `d3-scale-radial.js` plugin implementing a square-root scale for the radial variable, while `d3.arc()` generates the annular segments with `d3.stack()` for layered series. State labels rotate around the perimeter, and circle gridlines with tick marks indicate population totals. Data loads from a CSV file, rendered as SVG in a 960×960 viewport.

Radial Normalized Stacked Bar

This radial chart displays the age distribution of each US state as a circular ring of normalized stacked bars, with each bar representing a state and its segments showing the proportion of seven age groups. The outer radius encodes the relative share of residents under five years old, which determines the state sorting order. Built with D3 v4, it uses `d3.scaleBand` for angular positions, `d3.scaleRadial` (a custom d3-scale plugin) for radii, and `d3.stack` with `stackOffsetExpand` to normalize the data from a CSV file. Labels rotate around the circle, and a legend identifies the age categories.

Radial Stacked Bar

This radial variant of a stacked bar chart arranges age-group segments around a circular axis, with bar length encoding population counts. It uses d3.scaleBand for the angular axis and a custom radial scale for the radius, rendering the 51 U.S. states’ age distributions as concentric, ring-like bars. The code notes that while visually striking, radial bars are harder to compare than standard linear stacked bars, and recommends this form only when the ordinal axis is cyclical. The data here is not cyclical, making the radial encoding somewhat gratuitous. The visualization uses D3 v4 with SVG, and includes a custom d3-scale-radial module for radial scaling. The chart is interactive-free and rendered at 960x960, with a legend implied by the CSV columns.
