Donut chart

This donut chart visualizes a percentage value (47%) using a segmented arc, with blue segments representing the data portion and grey segments as the background track. The chart is rendered as SVG, with each of the 20 segments drawn as a path using the d3.arc function. The code calculates segment counts and a partial final segment based on the value, and applies stroke spacing between arcs to create the separated ring effect. The visualization uses React with D3 v5 for rendering.

This visualization displays a radial, donut-like chart composed of eight concentric arcs, each representing a different data item stacked from a single-row dataset. The arcs are rendered using D3’s `arc` generator, with their inner and outer radii mapped through a linear scale (`scaleLinear`) to encode values, while the start and end angles are fixed to create a partial ring. The SVG is drawn in React, and the stacked data is computed with `d3.stack()`. Each arc segment is assigned a distinct color from a predefined array, producing a nested multi-layered ring visualization.

Donut Example

A donut chart displays five randomly generated numeric values as proportional arcs, with each slice labeled by its value in white text. The visualization updates its data on button press or when the data reference changes, demonstrating a React hook-based update pattern. Built with D3 v5 and React, the `Pie` component uses `d3.pie()` for arc generation, `d3.arc()` with configurable inner and outer radii, and a `scaleOrdinal` color scheme. SVG rendering occurs within a React component using `useRef` and `useEffect` hooks to manage the D3 selection lifecycle.

Donut chart

A donut chart displays a single numeric value of 47 as a proportion of 100, rendered with 20 equal arc segments around a central hole. Blue segments represent the value, while grey segments show the remainder, with a partial blue arc for the fractional part. Built with React and D3 v5, the code uses the `d3.arc` API to generate SVG paths, setting inner and outer radii from the SVG height, and computes angles via `Math.PI` divisions. The SVG element is selected with `d3.select`, and strokes create separation between segments.

Donut chart

A donut chart displays the value 27 as a proportion of 20 total segments, with blue arcs marking each increment of five and a partial blue arc representing the remainder. The visualization renders in SVG using React and D3 v5, calling the `arc` generator to draw each path. The chart is built by looping through 20 equal segments, filling grey arcs for the unselected portion and blue arcs for the selected value, with white strokes separating each slice.

This example shows a donut chart that visualizes a small dataset of five categorical values, with each slice colored distinctly and separated by black strokes. The chart uses D3.js version 6, where `d3.pie()` computes the arc angles from the data and `d3.arc()` generates the SVG path geometries with an inner radius creating the donut hole. A color scale via `d3.scaleOrdinal()` maps each category to a unique color, while the SVG rendering is sized and centered within a fixed 450×450 viewport. The slices are semi-transparent and rendered as SVG path elements appended to a grouped container.

donut

This donut chart uses D3 version 6 to render a single, five-segment ring where each segment is a wedge of equal value. The visualization employs `d3.arc` with dynamically calculated inner and outer radii based on the segment index, and `d3.pie` to compute the arc geometry. Each wedge is filled with a color from `d3.scaleSequential` using the `d3.interpolateRainbow` palette, and labeled with its data index. The entire SVG group is positioned using a CSS transform, though the code’s intended rotation animation is present but not functional, as the rotation angle is fixed to zero.

Rendering data with react and D3

A donut chart renders the CSS named colors dataset, loaded from a GitHub gist as CSV, with each color name represented by a slice colored by its RGB hex value. The React component uses the `useState` and `useEffect` hooks to fetch and store the data asynchronously, then maps it through D3's `pie()` layout and `arc()` generator to produce SVG paths. All slices have equal value, creating a uniform ring, and the chart appears at the center of a 960×500 SVG canvas.
