This example demonstrates a reusable pie chart built with D3.js v5, following the patterns from Mike Bostock's "Towards Reusable Charts" and the Pro D3.js methodology. It renders two separate pie charts within a single SVG container, using `d3.pie` and `d3.arc` to calculate and draw the slices with an inner radius for a donut effect. The chart includes a title and uses `d3.scaleOrdinal` with the category10 color scheme to distinguish data categories. The code shows a modular structure with separate functions for building the layout, shape, scales, and SVG, allowing the chart to be easily reused with different datasets.

Simple Pie Chart:

A vanilla HTML implementation of a reusable version of tutorials teacher V5 example (https://www.tutorialsteacher.com/d3js/create-pie-chart-using-d3js).

The reusable chart is derived from Mike Bostock's Towards Reusable Charts (https://bost.ocks.org/mike/chart/) as the source of the foundational principles. But uses the ProD3 pattern (Pro D3.js Use D3.js to Create Maintainable, Modular, and Testable Charts by Marcos Iglesias https://www.apress.com/gp/book/9781484252024) as the basis for the charts.

Reusable Examples - Pie Chart 2

A reusable pie chart displays browser usage percentages from a CSV file, with a legend of seven categories and labels positioned between the inner and outer radii. Built with D3 v5 using the ProD3 pattern, the chart leverages `d3.pie()` and `d3.arc()` to generate SVG arc paths, with `d3.scaleOrdinal` and `d3.schemeCategory10` for color encoding. The implementation follows a modular structure with configurable margins, dimensions, and title, rendering via an SVG container.

Fork of Step 1 - A Basic Pie Chart

This example shows a basic pie chart created with D3 v4, rendering an SVG visualization of four labeled data categories with proportional slice sizes and distinct colors from the Category 20b scheme. The code loads D3 via UNPKG, uses `d3.select`, `d3.arc`, `d3.pie`, and `d3.scaleOrdinal` to generate the chart dynamically from a JavaScript array of label-count pairs. The repository also includes a separate Canvas-based pie chart implementation in `pie.js`, which draws segments and labels using context methods like `arc`, `fillText`, and `rect`, with data defined in a Module.

React Starter with Pie

This example demonstrates a donut chart built with React and D3, displaying a small categorical dataset with five segments. It uses D3’s `pie` and `arc` functions to compute the angular positions and draw the SVG paths, while `scaleOrdinal` assigns a fixed color palette to each category. The chart is rendered inside a React component, with D3’s `select` and `append` methods managing the SVG elements directly within the React-rendered container. The code also includes a separate `useData` hook for loading CSV data, though the pie chart itself uses inline dummy data.

Pie Multiples

Four small donut charts display proportional breakdowns for each row of a two-dimensional numeric array. D3 v3’s `d3.layout.pie` computes arc angles, while `d3.svg.arc` renders the path shapes. Each chart uses an inner and outer radius, with colors assigned by index from `d3.scale.category20c()`. The SVG elements are generated per row, and the totals for each row differ.

D3 Layouts - Pie charts

This example shows a donut-shaped pie chart that visualizes a small dataset of six numeric values. The chart is rendered as an SVG, with each value displayed as a white label at the centroid of its corresponding arc. The code uses D3’s `pie` layout generator to compute the arc segments, `d3.arc` to define the ring’s inner and outer radii, and `d3.scaleOrdinal` with `d3.schemeCategory10` to assign categorical colors. The chart is drawn using D3’s select/append API on a blank HTML page.

Pie chart in React & D3 - donations data

This example shows a donut chart of donation distribution across five categories—Health, Support, Education, Poverty reduction, and Other—with each slice labeled by its percentage. The visualization is built with React functional components and D3 v6, using `d3.pie()` to compute arc angles and `d3.arc()` to generate SVG path geometry. Slice colors derive from a categorical interpolation via `d3.interpolateRgb`, linking the data’s category order to a warm-to-cool gradient. The chart renders as SVG, with the React state and component structure managing the mapping from data to visual elements.

Pie chart in React & D3 - 1st attempt

This example shows a donut-style pie chart built as a React component, with four slices colored along a gradient from orange to deep pink using `d3.interpolateRgb`. It relies on `d3.pie()` to compute the slice angles and `d3.arc()` with both inner and outer radii to generate SVG `<path>` elements. The chart is rendered inside a `<g>` group translated to the center of an SVG canvas, with a commented-out companion component that would draw color swatches via `d3.interpolateRgb` for testing.

Pie chart

This pie chart example shows a donut-shaped chart with a solid orange center, rendered as an SVG using D3 v5. The chart displays four data segments (10, 20, 30, 60) with a color scale based on `d3.scaleOrdinal`, while radio buttons allow switching between apple and orange datasets (though only the orange dataset is actively rendered). The visualization uses `d3.arc()` to generate both the outer ring and inner circle paths, with the chart positioned at three-fifths of the SVG height.
