This example shows a donut chart built with D3.js, displaying six numeric values as colored arc segments arranged around a central hole. Each segment is labeled with its corresponding value, positioned at the centroid of the arc. The visualization uses the `d3.pie()` layout to compute the angles and `d3.arc()` to generate the SVG path shapes, with an ordinal color scale (`d3.scaleOrdinal` and `d3.schemeCategory10`) assigning colors. Data is hardcoded as an array, and all rendering is done via SVG elements in d3.v4.

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.

D3 Piechart

This example shows a simple pie chart built from a static array of six numeric values, rendered as filled orange arcs with white strokes on an SVG canvas. The chart is generated using the d3 pie generator to compute arc segments, while the d3 arc generator defines the inner and outer radii for the donut-style shape. The visualization uses d3’s select and join methods to bind the computed arc data to SVG path elements, with styling applied through CSS and inline attributes.

donut chart

This donut chart displays three proportional values as colored arc segments, with percentage labels positioned outside the chart. The visualization uses D3 v4’s `d3.pie()` and `d3.arc()` functions to compute segment angles and paths, rendering the SVG chart dynamically. An interactive element positions HTML labels via absolute styling, calculating their coordinates from the arc centroids and canvas dimensions. The static data is embedded in the code, with colors and suffixes defined per segment. Bare bones and functional, it demonstrates a simple, clean alternative to a standard pie chart.

D3 Piechart - with labels

This example shows a pie chart of fruit quantities, with each slice labeled by its fruit name. The chart uses the `d3.pie()` generator to compute arc data, and `d3.arc()` with inner and outer radii to create a donut-like shape. Slice paths are rendered in orange with white strokes, and labels are positioned at each arc’s centroid using `arcGenerator.centroid(d)`. Data is hard-coded in the JavaScript, and the visualization is drawn as SVG within an HTML page, styled by CSS.

D3 Piechart - Semi Circular

This example displays a semi-circular pie chart, also known as a donut chart, rendered as SVG. Six data values are visualized as orange arcs with white strokes, arranged from left to right across a half-circle. The visualization uses the d3 pie generator, configured with start and end angles to create the semi-circular shape, and the d3 arc generator to define the inner and outer radii. The arcs are drawn as SVG path elements using the `d3.select` API.

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.

Pie chart with labels

This pie chart displays three categories (A, B, C) as a donut, with each slice labeled by its numeric value and connected to the slice via a thin pointer line. Built with D3 v3, it uses `d3.layout.pie` to compute angles, `d3.svg.arc` with an inner radius for the donut shape, and `d3.scale.category20` for slice colors. Labels are positioned outside the chart using trigonometry on start and end angles, with anchors adjusted based on text bounding boxes. The data is hardcoded in the script.

Shapes: Pie Example

This example displays a small pie chart built from an array of seven numeric values, with each slice sized proportionally to its value. The visualization uses D3 v4’s `d3.scaleOrdinal` with the `d3.schemaCategory10` color palette to assign distinct colors to each segment. The chart is rendered as an SVG element, where the arcs are generated using the `d3.arc` API with an inner radius of zero and an outer radius of ten, and angles are computed via `d3.pie()` before being passed to the arc’s start and end angle functions. The data itself is hard-coded in the script, and the code originates from a gist by DanielAguirre, structured for use with Blockbuilder.
