This visualization presents a small multiples grid of polar area charts, one for each country, where each chart uses wedge size to encode the population of different religious groups. The code builds these SVG charts with D3.js, using nested selections, a pie layout, and an arc generator, and colors each religious group via a categorical scale. It loads data from a CSV file of the Pew Research Center’s Global Religious Landscape dataset. While visually crowded and hard to read, the example includes an interactive color legend that re-sorts the country charts when a religion is clicked, demonstrating a starting point for further exploration.

AI-generated description

A small multiples visualization of polar area charts showing the breakdown of religions for all countries. This is a variation derived from example 30 from the screencast Splitting Charts.

This visualization is useless, in the sense that it is not very readable. It has many issues, such as occlusion, but it does show the data for all countries on earth. This example gives a starting point for exploring how this data can be visualized more effectively. Please fork this block and experiment!

Data from Pew Research Center Global Religious Landscape data set
Uses d3-legend

D3 Example

A small multiples visualization of polar area charts displays the breakdown of religious populations across countries, with each pie chart positioned around a central circle and sized by population. The view animates country charts into place and supports clicking the color legend to re-rank countries by the selected religion’s population. Built with D3.js and SVG, the code uses nested selections, `d3.layout.pie`, `d3.svg.arc`, and ordinal, sqrt, and category color scales, with data from the Pew Research Center’s Global Religious Landscape dataset.

D3 Example

This example uses nested selections to render a small multiples grid of polar area charts, each representing the distribution of religious affiliations by population for a single country. The visualization draws from the Pew Research Center’s Global Religious Landscape dataset and sorts countries by the total population of a selected religion, which can be chosen by clicking a color legend. The code relies on `d3.layout.pie`, `d3.svg.arc`, and `d3.legend.color` to build the SVG charts, with animated transitions applied to reorder and reposition the pies.

D3 Example

This example visualizes the breakdown of religious affiliations across the five most populous countries using a small multiples layout of polar area charts, where each country appears as a separate circular chart and each segment’s radius encodes the population of a given religion. The visualization is rendered with SVG, using D3’s nested selections to group data by country and a pie layout to generate slices. The code explicitly uses `d3.layout.pie`, `d3.svg.arc`, `d3.nest`, and ordinal and sqrt scales, while the color legend is built with the d3-legend library. Data comes from the Pew Research Center Global Religious Landscape dataset, loaded from a CSV file.

D3 Example

This is a small-multiples visualization of pie charts showing the religious breakdown of the five most populous countries. Each country’s donut chart displays the proportion of its population following each religion, but the charts are all the same size, so area is not proportional to population, which can be misleading. The code uses D3’s `d3.layout.pie` and `d3.svg.arc` to generate the slices, with nested selections binding data to each chart. It also employs the d3-legend library for the color legend and renders as SVG. Data comes from the Pew Research Center’s Global Religious Landscape dataset.

D3 Example

This example shows small multiples pie charts comparing the religious breakdown of the world’s five most populous countries, with each pie’s area scaled proportionally to that country’s total population. The visualization uses D3’s nested selections and d3.layout.pie with d3.svg.arc to draw the charts, d3.scale.sqrt for the population-based radius, and d3.legend.color for the categorical color key. Data comes from the Pew Research Center’s Global Religious Landscape dataset, loaded from a CSV file.

D3 Example

This visualization displays small multiples of donut charts, one per country, showing the religious breakdown of the five most populous nations. Each donut uses the same fixed radius, so the charts show only the proportion of religions within each country, not the total population, making the visual misleading for cross-country comparison. The code uses D3’s `d3.layout.pie` and `d3.svg.arc` to generate the slices, with nested selections via `d3.nest()` to group data by country. A color legend from `d3-legend` maps religions to colors, and the data comes from the Pew Research Center’s Global Religious Landscape dataset, loaded from a CSV file.

D3 Example

This small multiples visualization uses donut charts to show the religious breakdown of the five most populous countries. Each donut represents a country, with slices sized by the proportion of followers of each religion within that country, though the donuts themselves are equal-sized regardless of population. The code uses D3.js (v3) with `d3.layout.pie`, `d3.svg.arc`, and `d3.nest` for data grouping, plus the d3-legend library for the color legend. Data comes from the Pew Research Center’s Global Religious Landscape dataset, rendered as SVG.

D3 Example

A polar area diagram displays the world’s religious populations, with each slice’s area proportional to its data value and colored by religion via a categorical color legend. Built with D3.js and d3-legend, it uses `d3.layout.pie`, `d3.svg.arc`, and a square-root scale to compute radii. Data comes from a CSV of Pew Research Center figures, rendered as SVG with a custom x-axis label.
