This example demonstrates a polar area chart that visualizes the popularity of nine programming languages, with each sector’s radius representing a randomly generated value. The chart updates every 20 seconds with fresh data, and hovering over a sector displays its current value in a separate message area. Built using the d3-ez reusable chart library, it employs the `d3.ez.chart.polarAreaChart()` API, along with `d3.ez.base()` for the overall layout, a legend component, and a title component. The data is generated client-side via a custom `randomDataset()` function, and animation is achieved through the `setInterval()` update loop.

d3-ez : Polar Area Chart Example

Generated using d3-ez D3 Reusable Chart Library

The Polar Area chart is similar to a usual pie chart, except sectors are equal angles and differ rather in how far each sector extends from the center of the circle. The polar area diagram is used to plot cyclic phenomena (e.g., count of deaths by month).

FUNCTION: Comparison; Trend over time

This example presents a top-10 programming languages chart as an interactive scatter plot, showing the 2024 market share percentages from `data.csv`. Each language is a black circle positioned on an x/y grid; clicking a circle turns it white with a black outline. The visualization uses React with D3 v7, employing `renderCircles` with `scaleLinear` for axes and click handlers for selection. An SVG pie chart with a legend is also available via `pieChart`, using `pie` and `arc` with `scaleOrdinal` and `schemeTableau10` for coloring.

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

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.

D3 Example

This example displays a small multiples visualization of polar area charts, showing the breakdown of religious populations for every country on Earth. The code renders each country as a separate pie chart, with the arc radii scaled to population size and colored by religion using D3's SVG rendering and the d3-legend library. The visualization is explicitly noted as difficult to read due to occlusion but offers a starting point for exploring the Pew Research data. Users can click the color legend to re-sort countries by the selected religion's population.

D3 Example

This visualization shows small multiples of polar area charts comparing the religious breakdown of the five most populous countries, with each slice sized by population and colored by religion. Using D3.js and d3-legend, the code applies nested selections and a pie layout, with a square-root radius scale to encode values. The chart renders in SVG and pulls data from the Pew Research Center Global Religious Landscape dataset, including a color legend for religion categories.

Bar chart with D3.js

This bar chart displays the popularity percentages of programming languages, showing the distribution of values across categorical labels. Built with D3 v5, the visualization renders SVG bars with axes, gridlines, and value labels. Hovering over a bar triggers a mouseenter event that highlights the selected bar, draws a dashed reference line, and displays divergence percentages for all other bars relative to the hovered one. The mouseleave event removes these annotations, restoring the original view. Data is loaded from a CSV file using d3.csv.

Bar chart with D3.js

This bar chart visualizes the popularity of programming languages using data from Stack Overflow’s 2019 survey. Hovering over a bar highlights it and displays the percentage difference between the hovered language’s value and every other language’s value, with a dashed reference line marking the selected baseline. The visualization uses D3.js v5 with SVG rendering, employing `d3.scaleBand` and `d3.scaleLinear` for axes, and `d3.axisLeft`/`d3.axisBottom` for gridlines and ticks. Interactive transitions via `d3.transition()` animate opacity changes on mouseenter and mouseleave events.

ICE7

This interactive pie chart visualizes the distribution of the top 10 programming languages of 2024, with each slice’s size proportional to its usage percentage and a legend on the right listing each language with its exact value. Built as a reusable chart function using the `d3.pie` layout and `d3.arc` generators, it assigns categorical colors via `d3.scaleOrdinal` and `d3.schemeTableau10`. The React application loads the CSV dataset and renders the SVG to fill the browser window, labeling slices with values above 3%.
